Have had some trouble with steering wheel vibrations lately. Think I had a few bad balances but the last place I went to was adamant that wheels were perfectly round and balanced up (I watched them balance the wheels myself).
So here is the problem; Wheel shakes at 90km/h at times but then is ok at others. Will also shake at 110km/h at times off and on. Car also pulls hard to the left at times but after hitting a small bump will correct itself.
Had a quick look over the car and there is definitely something going on with one of the coilovers (drivers side front). With the Nut at the top of the coilover done up there is a 5mm gap between the damper adjuster and nut (which is not on the passenger side). Apart from that the coilovers seem to be tight.
Lower control arms also look good with no play.
Caster arms have polyurethane bushes in them and again have no play.
Steering rack mounts look old as well but again there is no play when I try to shake it.
Steering column has the factory rubber bushing and does actually move around a lot...so was thinking that could be a possible cause but not really convinced.
The ball joints of the outer tie rods have flogged out dust covers and therefore contain a lot of sand, however there is no play. I have yet to disconnect the tie rods to see if the inner joints are flogged as well.
Also did a google search and found that a common cause of steering wheel vibration in s13's was a worn out tension spring in the steering rack.
Plan is to attempt to sort the problem out by looking at issues in this order:
- Replace spring (as its a cheap $7 part)
- Replace steering column bushing with a solid bushing (again cheaper part at <$40)
- Take car to suspension shop to get the drivers side coilover looked at
- Have a second look at the tie rods and disconnect them from the knuckles. See if I can clean up the outer ball joints and get away with just replacing the dust covers.
- Replace steering rack mounts with polyurethane ones.
Is there anything else that I have not considered?
