D2 Steering Shudder

[Hendrik]

I've been experiencing a very noticable shudder on the steering wheel, when driving around at low speeds, usually between 40 and 60. I've replaced all the tyrod ends, which were worn, still the same problem. Furthermore, at cruising speed you can really feel a vibration on the backrest of both the driver's seat and and passenger's seat. Now I've had the wheels balanced, balanced the front prop shaft, and that made it slightly better, but there is still that noticable overall vibration and steering shudder. The only other thing i can think of is a bent rim, but surely the guys who balanced the wheels would have picked it up.

Any advice would be greatly appreciated

Check that your tyres are not out of round or flat-spotted.

The steering damper could be shot as well.

Broken engine mount, or flex joint on the exhaust, radius arm bushes.

I know you say you had the prop shaft balanced, but were the unis on the Double Cardan joint checked for wear??

You could also check the panhard rod bushes. unlikely to be the issue but possible.

[Hendrik]

When I had the prop shaft balanced, the uni's were checked and was all still fine. Ill investigate the flex joint on the exhaust see if thats a problem.

Does the vibration come on under load or when you're coasting? Auto or manual?

I hate to say it but I started getting a similar 'sounding' vibration when my auto was about to go bang. The speeds were higher though.

[Hendrik]

It occurs when coasting, and its a manual, so hopefully it wont go bang...

[Redback]

The only other things i can think of are, the shock mounts, see if there tight, rear drive shaft, front diff pinion bearing.

I'm only guessing though, i did have a wobble in the front and a vibration from a loose shock mount, after tightening it, it got rid of the wobble and a bit of the vibration, the rest of the vibration was the front prop shaft:mad:

Mine is a manual also.

At my 90000K service was told (MRAuto, Redcliffe) that my engine mounts needed replacing,(there big rubber thingies that flatten out) and that I could wait until the 100000K to have them done BUT i may start to feel steering vibration. This never happened but I had them done anyway, not an expensive job. I think this problem was mentioned on AULRO some time ago and rectified by replacing engine mounts.

would the collapsed engine mounts be really easy to notice though?
I had a look earlier today and the rubbers on both sides still feel fine.
Also, could this also explain the vibration experienced in the front seats and the sometime viscious shaking of the gear lever in 5th gear?

Thanks Steve. i have a s1 disco & have rebilt f axil almost got rid of steer vibration. i'll check the engine mounts now.

When I was advised to replace the engine mounts after the 90000K servive I hopped under when at home, yeh OK really meant nothing as the mounts "looked" OK BUT after being replaced at the 100000K servive and hopping under when at home, well, much beefier rubber, at least double the size, so I guess over time they just flatten out with all that weight etc. and become ineffective in dampening engine vibes through the chassis.

Well at 230000 km and never done i'd better look at them

[Hendrik]

So would replacing these rubbers be a difficult job? how much are these rubber generally?

[Redback]

D2 engine mounts are expensive, around the $300+ mark, if the mounts are shot, you should feel a vibration at idle.

LR no that they cant make a engine mount that lasts, so they put to inpection holes at the bottem of the mount, if you thru the holes, and see rubber is touching or very close to the bottem of the mount,, there stuffed,

[Baffle]

Had this problem, buggered my mind for a while including a LR mechanic , replaced the watts link bushes and all is well :cool: worth a go, not to hard to do.

This is exactly what I went through, just re read your post. Give it a go , and replace the bolts also as they wear on the watts also. Good luck
