Steering SWAYS alot at highway speeds. Very Scary to Drive

I replaced the inner and outter tie rods two weeks ago.
I DO need to get the allignment done.

However, my throwout bearing somehow bounced off and I had to replace the whole clutch assembly last weekend.

Now that I am back on the road, I still have a hell of a hard time keeping the car from swaying when I hit curves in the road or water on the highway at speeds greater than 50. I did not get the alignment yet.

The steering sloppiness is gone thanks to the new tierods, but the steering wheel is VERY VERY easy to turn at highway speeds. I did read about the rack and pinion adjustment nut, as this is supposed to stiffen the steering wheel back up. I want to try this, however, finding the damned 43mm wrench for the job has been hard to find.

They had me on a 30 day waiting period to have it shipped from Japan.

Anyway, I read about the adjustment and how it helped this guy at Steering rack adjustment - Best thing I ever did. - Honda-Tech .

I want to do this, however, if it is going to need a new rack and pinion, I'd rather just do that then waste 100 bucks on an alignment.


So to recap:
Replaced tierods and I want to know if this rack and pinion adjustment bolt will fix my very easy-to-turn steering at highway speeds.

I even read about the VSS (vehicle speed sensor) needing to be replaced if the wheel is too easy to turn at highway speeds.

Any input on this is greatly appreciated. Thanks guys.

Yeah i did this on my integra Da before my steering wheel shakes like hell even i did alingment new tires etc then my friend told me about how to adjust the steering wheel rack and pinion. it works really well after that i can drive faster than before. you should try it it wouldnt hurt for my experience and my advice try that first then after do the alignment but its up to you.

Re: Steering SWAYS alot at highway speeds. Very Scary to Drive

I feel like I may have a similar problem. Does it feel like the car is tracking really bad at these speeds? Mine will randomly want to jolt to one side or the other for no reason. Definitely doesn't feel safe. If we do have the same problem, I got an alignment recently and hardly noticed any changes.

try it you will notice a big difference on highway drive im gonna do that next week ounce i get time off at work i noticed mine is kinda loose even i just recently changed my tie rod ends and my upper control arms. ounce i passed 75mph hell it feels like my wheels are coming off or something lol. anyways its not that hard to do it you just need a 40mm specialty honda tool so you can adjust the tightness on your rack and pinion.

If you jack your car up, and try to wiggle the wheel, does it "click" up and down, side to side, or diagonally

Re: Steering SWAYS alot at highway speeds. Very Scary to Drive

Well, some people say it's 40mm, yet my manual (the actual HONDA Prelude repair manual) says the nut is 43mm. I am going to take the cover off tomorrow after work so that I can get a good look at it.

Since the damn clutch went last weekend and the tierods had to be repaired the week before, i havent even had a chance to look at it.

Let's put it this way: Tuesday (this morning) I have a 2.5 hour commute to work. It rained slightly and the damn car felt like it was going to throw me off the road if I went faster than 45. I noticed my one tire is slightly toed out so I know this is definitely a factor for the recent aggressiveness of the swaying. It was always bad in the rain but NEVER this bad.

Anywho, I also noticed in the HONDA manual that it could also be the Valve Body Unit (attached to the rack and pinion).

The troubleshooting section mentions that if the car is suffering from "Assist (excessively light steering) at high speed" that you should measure the force required to turn the wheel with the car on a dry paved surface.

You would have to take off the hoses to the VSS (Vehicle Speed Sensor) and bypass them. Then you would tie a spring gauge to the steering wheel and measure how much force it is to turn the wheel until a tire begins to turn. If it is below 50N (11lbs) then it could be the pump (not in my case), a bent feed line (not in my case), or the valve body unit.

I don't really have the spare tubing or anything to bypass the hoses, but I would definitely like to look into this further.

I am going to document this through the whole process because I know I'm not the only one out there with this issue. I will also try to take as many pics as well.

Good news is that the valve body unit is VERY easy to get to, so if that is the culprit, I just have to look into how much it would be to replace it.

If I could just find a way to get into the rack and pinion to get to the adjustment bolt... If anyone knows of a website that sells the special tool, let me know as well.

Thanks in advance.

Also, its a good idea to check your tires for movement (as mentioned above). My front tires had a crap-ton of play from 3 to 9 o'clock, meaning it was most likely the tie rods (which it was in my case). If it was moving from 6 to 12, then it would be an upper or lower balljoint.

However, fixing these issues did not fix my high speed sway... I miss being able to have fun driving my car. I'm always scared any more lol.

I'll be posting an update tomorrow evening.

God bless ya

Re: Steering SWAYS alot at highway speeds. Very Scary to Drive

If its the back end swaying around then its somthing to do with suspension for sure. If your can is lowered or was lowered, chances are it bent somthing. I had this problem with mine when i bought it. The camber and toe were off too much to fix with an alighnment. I wish i could tell you the exact bent item for mine but i was able to pull a whole rear subframe from a parted car on cl and swap it out with mine and that fixed the problem. Check control arms and ball joints. Im not sure how to tell if the are straight or bent but they take maybe half hour tops to replace.

Re: Steering SWAYS alot at highway speeds. Very Scary to Drive

For the first time in months, I CAN'T WAIT TO DRIVE MY CAR TOMORROW!

First of all, I was trying to get my tires somewhat aligned at a local shop, yet they wouldn't do it. I just wanted them to correct the toe out for a cheap fix, since I have to replace my intermediate shaft this weekend thanks to a bad bearing AGAIN (3rd time) and I would need an alignment again after that. Street Imports - Home is replacing it under a warranty. They mentioned a car with bad camber alignment can really tear up the intermediate shaft bearing.

Anyways, I found a video on youtube that explained fixing toe in / toe out alignment and I was able to get my tires within an 8th of an inch perfect (slightly toed in). I found out that my tires were a total inch toed out prior to me fixing it!! No wonder I was getting thrown all over the place more than normal.

But that's not the best news. I took off the cover to the power steering valve body (under the driver side behind the tire), and I was able to loosen the adjusting nut without loosening the 43mm locknut.

I DO NOT RECOMMEND DOING THIS!! I'm not trying to ruin someones rack and pinion by my directions. However, mine just so happened to be SO loose that the adjustable bolt AND the locknut loosened at the same time.

I was able to tighten it AT LEAST 2 FULL TURNS. Way off from specs.

I tightened it until it bottomed out, loosened it, then tightened it, then turned it out an 8th of a turn. When I took it for a test drive, the steering was WAY too tight and very jumpy.

Since I couldnt get to the locknut to tighten it snug, I was able to adjust the bolt without jacking the car back up or taking the cover off.

Anyway, I loosened it at least 1/4 of a turn and tried that.

I took it on the highway and to my absolute surprise there was NO MORE SHAKING or SWAYING! The car drove incredible and my steering wheel was much more snug than before.

I was unable to take pictures, but the other forum had GREAT pictures already in it and the guide is much more in depth.

I just wanted to write back and report how great of a difference changing my tie rods (which were beat to hell) and adjusting this bolt for the steering rack.

I will report back tomorrow after work for a full day's worth of driving. (I drive a minimum of two hours tmrw on windy roads).

Re: Steering SWAYS alot at highway speeds. Very Scary to Drive

Update:

Drove an hour into work today and I was cornering turns at high speeds like I used to do!

Definitely was the best thing I ever did to my steering system of the car.

The new tierods stiffened the wheel to no slop.

I may try to tighten the adjustable nut slightly more, but if it stays the way it is, I'm absolutely satisfied.

Just make sure not to OVERtighten, as I said before, this will cause damage to your rack and pinion by wearing down parts. You know if it is too tight by turning the wheel all the way left and all the way right: if it gets real tight then "jumps" and then tight again, you know you cranked it down too much.

The directions state to tighten it til it bottoms out (and loosen and repeat), this will help reseat the spring that's in there properly.

More feedback later.

Hey bud, sorry for the delay.
I ended up not needing the tool. Mine was so loose that when I loosened the adjusting nut (14mm), the locknut loosened with it.

I then loosened the locknut by hand, did the adjustment as stated above, and then tightened the locknut with a set of channel-locks.

It was so easy to loosen and tighten, I would attempt to do it without buying the tool.

Mine was stated as a 43mm in the manual.

UPDATE: I got my alignment done (well, they fixed the Toe In / Toe Out... the Camber is 4 degrees out and I need a camber kit)... and I got brand new tires in the front.

I have been whipping my car around country roads for a whole week and its never been so enjoyable since I bought the car in 2004.

This solved everything.


I'm going to start a new thread because now I have issues with my alignment.
The front is out 4 degrees camber, and the rear is out 4 on the left and 2 on the rear right. The rear also has a slight toe in which apparently is non-adjustable.

The guy told me it would cost 1000 bucks to fix so I want to look into this further.

Any feedback is greatly appreciated.

Re: Steering SWAYS alot at highway speeds. Very Scary to Drive

Just FYI for anyone that needs this info, there is indeed a Lock Nut 43mm wrench for the 4th gen Prelude (maybe 5th too and others?). Itís part number was: 07MAA-SL0020A But itís been superseded to: 07AAA-STKA100. Just oredered mine for about 30 bucks. Cheers to tight steering and no more clunking!
