got the shakes
Discussion
p38 with brand new tyres...new steering damper...all the front end checked by land rover garage.Still cant get rid of a steering shake at about 55mph.Doesnt feel like the normal wheel wobble you get with unbalanced wheels more like the front of the car starts to shake....any ideas out there.

"Steering Vibration / Shudder
The 4.0/4.6 has a much better steering box and system than the Classic. However it is of the same basic design, and some owners have reported the steering judders upon going over bumps at speed that are so notorious and common in Classic models. If you have checked out all the ball joints and tie rod ends, the most likely cause is the steering box needing adjustment. Like the Classic, the 4.0/4.6 steering box has an adjuster on top -- this one has a screw with an internal hex and locknut. Jack up the front wheels and screw in the adjuster until there is minimal play in the steering at dead center. Then turn the wheels lock to lock to make sure there are no tight spots. The other thing to check is the swivel pin bearings, which need to be kept adjusted as per the shop manual, or replaced. Ian Dugdale (Ian at Dugdales dot com) had this problem and after trying the usual remedies (suspension bushings, steering damper, etc) he replaced the swivel pin and steering joints and that made a huge difference. Also (and this needs to be done very carefully) he tightened the steering box slightly (about 1/8 turn). Overall that made a major improvement in the driveability of the vehicle. A member of the Range Rover forum, Rundeep_32, found 90% of his steering shudder went away when he replaced his shocks (he used Woodhead units sourced from DAP which appeared to have strong rebound damping and relatively mild comression damping)."
Also what do you mean by 'Land Rover garage' - franchised dealer, specialist non-franchised etc? And are they familiar with the P38?
Might be worth having a word with this chap - is mobile so comes to you.

Do you know what wheels they are ? Original P38 or newer type off Range Rover L322.
Newer wheels will fit a P38 as its the same stud pattern but the wheels are not held central so you need to fit a thin spigot ring ...so the wheels are located centrally on the hub.

You also get a vibration through the car if not fitted
