hi all i have a prob or rather the d-olly does
as i,m driving along,if a bump in the road comes along, the steering wheel vibrates/occilates at an alarming rate as do the front wheels- its like a spazm
it occurs afer a bump on the road surface, thats when it goes all crazy
the steering wheel vibrates and the front wheels go from side to side a bit
its always been ok up till now
it lasts for up to about 20- ish seconds appeciate any info fellas

Dampers/loose damper mounting plates, knackered kingpins or knackered track rod ends. Usually one of those.

I had the same problem on my '88 spesh. ......in my situation it turned out to be the track rod end "ball" which had worn a little.......there was no aparent wear on it [making it oval] so I simply greased it & tightened it up.
One word of warning .......when you replace the splitpin,replace it the same way that it was fitted [with the "U" part of the splitpin on the inside of the threaded tube/castelated nut] .....I inadvertently fitted mine the wrong way round,and the problem returned after about 20 miles.

Personal advice - stop driving it immediately. I had same problem, I pretty much ignored it like the penis I am, it vibrated so much that it sheared off the bolts that hold the track rod end lever arm onto the hub. Result, no steering, and very close to a head on.
Turned out to be buggered rack. Also needed new pants, trousers, seat and steam cleaning of interior.

With a knackered kingpin I experienced exactly what you describe, the juddering and vibrations at the front.

With no rear shock absorbers I experienced bouncy rear wheels, lack of grip and juddering, made the car horrid to drive.



Probably sound advice until you've isolated the problem.

Check your shock absorbers by jumping on the bumpers. The car should go down and bob back up without bouncing. If you get the boingy boingy clown car effect your shocks have had it.

Check the kingpins, jack up the front and have a wiggle, up and down as well as side to side.

If it's not either of those look at the track rod ends and rack.

Probably worth mentioning that it can the combined wear in various steering components which allows enough free movement for that uncontrollable oscillation to occur; you will need to check kingpins, track rod ends as well as rack slider and pinion for free play.

thanks for all the replys fellas the k/pins are quite new i reckon it might be the track rod end adjustment but ill check all the things mentioned tomorro

Wouldn't go jumping up and down on the bumpers as this tends to put chuffin great dents in them or even shear them off the mounts if they're rusty.....

i did have a foot on the front bumper tonight the bounce was a bit half and half the shockers maybye origional , they look old(like me)

Domt meed feet just push down on the bumper
