discovery problems !

[robert francis]

hi, my friends got a land rover discovery 300tdi off road prepped, and when he hits about 32mph the steering wheel shakes so bad you want to get out and walk home,
things weve changed,
front axle
steering bars
front bearings
 only happened after steering bars were changed, but we taken them off put another full set of track rod ends on and triple cheked alls done right and they are

does any one have any ideas

Check the bushes, all of the front ones
Are the front wheels bent or badly balanced?
Is the car lifted? Maybe the prop is under stress and vibrating
Castor correction may fix that problem
Are the wheel bearings properly seated?

[Thrasher]

try swapping the wheels/tyres with a known good set.

Steering damper?

[Lord Shagg-Pyle]

Steering damper?

Only when he drives through water! Sorry, couldn't resist that. Sounds like wheel balancing problems.

hi all thanks for your reponses, its got a 6"lift, and fitted with qt castor corretor arms, wheels bearings well in, and got scorpion racing props front and rear.
 and weve tried it with and without a pro comp steering damper, thanks guys il tell him about the tyres

Could be King pin bearings - you might not feel any play but worth stripping them and either repacking/adjusting them or changing. Would check wheel balance first though.

just a thought have you looked at the steering box or pump?? my 200 used to shake at 50 and i changed all bushes, put axle on it, steering damper, new track rods, Props, bearings, and it was a dodgy PAS pump that when you spun it it was notchy (it was causing the steering box to operate (ever so slightly) side to side on the road)

I had exactly the same experience with our local ATS (not the same results). They messed up the centring on my steering while replacing a track rod end so the car felt very strange indeed. Ended up having to take it to a main dealer to get it sorted out, luckily before it wrecked my tyres!
