YES I SEARCHED

The symptom is a vibration in the steering wheel and also feels like I can feel it through the pedals and possibly the floorboard, but its so faint there that I'm not sure its the same vibration or just normal road vibration. The vibration comes on at 60 and is quite nasty at 70.

Car setup in front, where vibration is:

Koni Yellow OTS Strut, Ground Control 450lb/in spring, CTR LCA/shock fork +CTR Sway Bar, 'Bolt style' adjustable UCA, Wilwood Dynatlite 4piston 12.19" (aluminum hat with bolted on rotor), ARP extended studs (I run 20mm H&R trak+ at autox, but not on the street). Alignment is set at -1.5* camber, 0 toe.

Here is what I have done so far:

1. New Wheels Studs
2. New Lower Ball Joints
3. New Wheel Bearings
4. New Brake Rotors, a replacement brand new from Wilwood for my Dynalite 12.19" kit.
5. New upper ball joints
6. Rotated and re balanced tires, ect.
7. Axles have about 10-15k miles on them
8. New inner tie rods

Here is what looks worn to me after inspection:
1. Outer tie rod ball joints

The bushings look o.k. to me, I haven't seen any wear and tear on them at all.

Anything else I should check?

I haven't checked the subframe bushings and I will check those bushings next, but I'm fairly sure those are the only ones I haven't checked.

 

check tires for cupping/feathering...
i had a similar symptom my tires were cupped on the inside

 

I have the same exact problem! I have changed everything as well except for axles. that is my next step

 

I had a issue like this, replaced everything. Turned out to be a bad bearing in the tranny.

 

checked the tires and rotated them, also don't see any feathering on them- is cupping the same thing?

I do have a slight tranny whine from a bearing, so I guess it could be that but the tranny and motor will be replaced soon. Super annoying.

Thanks for all the replies! Hopefully someone has some other ideas as well.

 

Do you have aftermarket mounts? My friends car does this do to them. Just a thought

 

what kind of wheel weights are you tires using?

i had my tires rebalanced with stick on wheel weights and my steering wheel vibration went completely away. Prior, it started to occur at 70 and i brought it up to 100 and no shake.

irregular wear on tires will cause steering vibration too.

 

I had the tires rebalanced, and the tire shop put stick on wheel weights on. I can try a rebalance again I guess.

Motor mounts are certainly a possibility.

 

I have a similar issue with my 93 Cx hatch. I'm replacing the front wheel bearings on Wednesday.

 

good luck, i hope that solves it! checking subframe bushings today. possibly taking it to the ever competent evan, who runs 360imports.net / 360 Imports tomorrow. I'm sure he will figure it out.

 

Wheel balancing first..the weights can fall off it adhesive is loose.

 

tried that once, might try it again at this point.

 

New wheel bearings cured my high speed vibrations.

 

Do u have aftermarket rims that are lug centric?.... just a possibility... I had a nasty vibration due to this and gotsome hubcentric rings... look online b4 u buy at a store its a fawkin rip off.

 

Get the tires road forced balanced if they aren't already, sometimes a tire will be junk but it will spin true with no signs of cupping or anything, those machines will say right away if there's too much road force

 

Any updates?

 

Axles can give a vibration, but mine smoothed out at certain speeds. Most aftermarket axles lack a balancer and get harmonics, though many do that from new. I noticed mine after an axle change. OEM with balancer, or Raxles are best, but not sure if this is your problem.

 

Another thought, tires could be bad, bulged, or rim not round. Hopefully you would also get this info spinning the tire for balancing, so not likely.

 

I have the same problem. . .

 

Do you have wheel spacers?ripoffs could be uneven which could cause the same..if you don't, try to clean the contact area of the wheels to make sure its flat and even.

 

hey i got sommin like this you say a bad bearing in trans huh.... what were the symptoms .. did your tranny make any noise and also did your car vibrate at 70 + and a slight whine ( hard to hear over motor noise) and did i vibrate on the left or right drive axle. also did you have a clunk-ish noise??

 

welp, im going to get my tires re balanced... but first i'm going to replace my motor mounts and my transmission (swap going in). ill update this thread when it gets fixed.

had the car up on the lift the other day and re checked everything again... nothing wrong. even had evan herling, the shop owner of 360 imports look at everything. wheel bearings aren't making noise, diff bearings seemed tight...... so still stumped but its gotta be something.

the vibration feels almost intermittent. itll go away and come back depending on the road sort of, but its almost worse on some smooth roads. confusing

 

I have a bent wheel. Fml. That was causing my vibration.

 

you rotated the tires front to back, correct?
i don't think it would be imbalanced tires, bad tires or bent rim then

 

Did you ever figure it out? I had a bad vibration on the highway only when I stepped on the gas. It was only on the driver side. Coasting it was fine. Took us forever to figure it out. The vibration felt like when your tires start to lose grip from a take off.

I had a the vibration for a long time and after months of diagnosing and checking and replacing parts. I gave up. We changed out tie rods, ALL bushings, rebalanced tires and checked tires, rotated tires did alignments and checked engine mounts and wheel bearings. Looked at the coilovers for blown struts. Things were either in spec or they were replaced if even slightly worn. Nothing worked.

One day a drive axle started clicking and we changed it with a brand new aftermarket axle. Vibration went away! Then Came back a month later. Just to test we replaced it with another brand new aftermarket drive axle. Vibration was still there.... As a last ditch attempt we had a used OEM axle laying around. We replaced it and the vibration went away and never came back. Check your axles. Especially the aftermarket ones. I will never use another aftermarket drive axle ever.

By the way those same vibrating axles were used to get a few friends cars going so they could get back on the road. guess what? They vibrate on their cars too. The "New" axles you get from auto zone and pep boys or any of the your local parts store are all made in china. Different boxes or names but probably all made by the same place.

Yes there is a lifetime warranty on them. But the headaches and vibrations just aren't worth it. Get OEM.
