Have a quick question: how badly does a slight misalignment still cause a steering wobble/pull when driving over potholes?

I hear a slight rattle from the suspension... worn shocks play a role?

Surprisingly a lot

Once the geometry is effected problems like noise....poor ride quality will be amplified several fold.......if it is so bad as to feel bumps ..etc through the steering wheel and components it will only get worse when driving faster

You also have the what I call the "Aggro" syndrome.....i.e....the more you become aware of it the more it annoys the brain.

Not forgetting the damn wallet and the Piggy Bank.

Had the alignment done but unfortunately it is still there...

Here is a list of things changed: tie rods, tie rod ends, lower arm ball joints and arb drop links.
Drop links were of type MOOG, the rest of type Meyle/Lemförder.

Still got me scratching my head...

Could it be some steering wheel play?
Having a slight doubt about the MOOG parts... though should I feel that also when cornering (which is fine)?

I noticed the shop took the alignment setup of a C25XE, not C20NE... does that play a role?

Cheers...

Hi all,

Recently got my front wheel with new tyres, wheels rebalanced and re-aligned for a second time, but to no avail...

This is what I'm seeing when the wheels are slightly off the ground:

http://www.icone-music.be/files/Calibra/FrontRightWheel.mp4

Not sure what I need to think of this... Probably wheels are not round (?) but VERY hard to see anything on the metal rims by eye... Or could this be created by something else?

This must be sending you up the wall.  >:(

The cost goes up and up and you just seam to be chucking money at it.........but sadly this will continue .......unless someone can pinpoint the problem.

There are only two possibilities I can offer but it is only a guess.............One is perhaps wheel bearing damage or collapse.............or Two

The drive shafts have bent out of true and are not straight.......with the amount of potholes we have to drive over each year it is these items i.e.

Suspension, ball joints, lower arms, wheel bearings that take a battering.


Finally if the wheel bearings and drive shafts ar ruled out then the problem could be down to ...the wheel hubs .......I say this because your video

Shows a definite uneven rotation.......could also be as you mentioned the wheels are not geometricaly round.

From your video evidence I hope you solve this agrivating problem......Good Luck.

I forgot to also check the Cv joints both sides.

Yeah it is darn frustrating!

Besides looking at how the wheels spin, are there any other telltale signs of either bearing or drive shaft failures?

My gut tells me to look at the bearings since the wheel also feels shimmy when driving uneven roads...

I have new bearings and drive shafts on order, going to look for seombody that can fit them now :)

Ah forgot to mention: when I let the car slide down the driveway without the engine started, or press the clutch during driving, the steering wheel shimminess remains... not sure if that reinforces my gut feeling its more related to the bearings.

The car has always vibrated a little on its own on idle which was very bearable... I did pointed that more towards some play or so in the driveshafts.

Swap the wheel around for a back one to see if it is buckled. I had an Alfa where the po had kerbed it at speed, the bearing did collapse and I had to change it. I think the driveshafts have balance weights/dampers from factory, see if they are missing. Check that the disc is true and not corroded to bits and unbalanced. Its a rotational thing causing the vibration, so it´s those parts that are suspect assuming no loose ball joints.

Cheers for the reply!

In fact I never saw any weights on the driveshafts with my 8v... would they have fallen off somewhere in the past?

the break discs are brand new... I don't see any visual offset on them while they are spinning. I swapped out the rims for another type and can see a slight difference, so I think some of it does relate to the rim itself.

On the ones in front, I can see a different motion between the two wheells. What's odd is that in the back I can see exactly the same... although switched per side. Say front left and right rear are pretty much the same... as are front right and rear left. I will try swapping out the left side front and back as well.

Will this sort of unbalance though also make the steering wheel much more sensitive on uneven roads?

Thanks again! Hope I'm getting closer...

If your getting bump steer on uneven roads, sure you haven´t kerbed it or dropped it in a pothole at speed?. I would get the measuring tape out and dial indicator find a flat floor and measure the lower wishbones on both sides looking out for twist, the early wishbones were weak. Also jack up the car and use a dial indicator for your rims, hub, and driveshaft before changing any parts. Crowbar all the joints to make sure no loose ball joints or bushes, and the nasty one to fix is the front sub frame mounting points, are they tight? If your removing the drive shafts take the opportunity to inspect the top mounts and top bearing, check the backlash in the steering rack too.

Cheers for the further advice!

Lower arms are pretty new actually... as well are tie rods and ends. Problem unfortunately was already there before. There was some up/down play in the rack so I also replaced it with a second hand which was still in good condition (without up/down play). Any small movement I do with the wheel I can see directly being captured by the wheels, so I don't think it's the rack...

So I'm pretty confident it's not any joints...

Will double-check front subframe bolts as well, cheers.

What would be a good dial indicator tool? Agree this would be helpful.

Dial indicators off evil bay or local independent good tool and machine shop or machine mart. need one with a least 1/2 inch (12mm) 1 thou (0.01mm) with a magnetic base  (or make one ) Their all fairly cheap and you can use them for everything including timing belt TDC. If you have a separate driveshaft bearing on the long driveshaft bolted to the back of the engine, check that. There should be near zero run out on a drive shaft, hub and brake disc. Check the bearing play in the hub and gearbox ends. Find something before you throw money at it !!

Make sure to check the hub side to side and the vertical to make sure it hasn't gone buckled. Wheels standard or aftermarket? aftermarket ones may all be completely shot unless top quality.

Finally look for creases, new paint in the front sub frame if the po has driven over a traffic island.

Thanks, will do!

I did try rocking the wheels around but could not get any play.m anywhere. The drive axle has a little play in it but it has pretty much always been there like this. The left qide drive shaft I can give it a slight back/forth movement as well. The right side also has a little play to the intermediate shaft.

Wheels are not originals, they are Ronal original GM/Opel 17" which came from a Corsa or so (ET44)... always drove pretty well.

Hi all,

So... just had my car checked by a friend working at an official dealer. He couldn't find any play in any joints, steering gear, bearings... also driveshafts had minimal play that couldn't cause this vibration.
He drove the car with me and was equally puzzled... told me the car still looked great for its age :)

We found one bolt on the steering gear mounting brackets that could be tightened a bit more. Drove it around, but no luck... judder is still there.
Have anyway ordered new mounting rubbers for the steering gear.

Grrr...
