Steering wheel shake + vibration

Moving on from the oil leaks I have a steering wheel shake around 60MPH so took the car to my local garage who have balanced all road wheels. Steering wheel shake still there. Took it back and they checked the steering and front suspension for faults and found none.

They took the car for a test drive and confirmed that the steering wheel has a bad shake and the whole car has a bad vibration at 60MPH but above or below that speed is fine.

My question is if the rear rubber prop-shaft coupling has gone could that cause the bad vibration and the steering wheel shake only at 60MPH ?

have you checked the steering damper

Yep, replaced with a new one hoping that would cure the problem.

What size Rims??

P38's are a bit iffy on anything above 18's and when running 18's, it can be a black art to getting the Pressures correct!

Not a clue , the car has the original wheels on that came with it when it was made in 1998.

Original Fitment was either 16 or 18...

A big clue to rim size .....

Could be the front ball joints worth a look

They are very sensitive to slight play in track rod and drag link ends.

What's puzzling me is it only does it around the 60MPH mark, above this or below this it is fine and does not seem to be revs related.

Mine had a session like that plus tramlining, went away with new TRE's. They are also very sensitive to tyre pressures, unloaded mine runs best at 28psi front and rear.

Mine does have a tendency on rough roads to go in what ever direction it wants so I have to correct the steering allot just to go in a straight line. Will get under the car at the weekend to check things out for my self.

It only needs a minute amount of play, hard to see.

60mph def seems wheel balance to me if you can drive through it,take it to another tyrebay and get em re checked/balanced incase there machine is out of calibration.p.s did they static balance them ?

Swap front and rear wheels over after checking pressures and signs of wear.

I had to get my wheels balanced twice to eliminate the same symptoms - shake between 55 - 65mph. P38's do seem sensitive to balancing.

They are sensitive to any sort of use, a bit like a menopausal woman

.....or pregnant women in my case

also check front & rear uj's on the propshafts

+1 wheel balance. Mine shook the passenger seat violently at 55. Fortunately the her indoors wasn't sat in it at the time. They need to balance them bang on.

it could be a buckled wheel, have experienced that nyself. car was fine around town, but on motorway started vibrating. when i had a puncture and ut my spare on it was fine. pot hole damage was the cause!
