Vibrations coming up Steering Column on CDTi
 

In my continuing quest to solve this problem, a local Land Rover specialist has suggested something to add to all the many suggestions via ths Forum. They think the rubber on the Lower Crankshaft Pully is deteriorating. This problem has occured on Freelanders (with the similar engine) and causes much "pulsing" of the steering column. Have any of you out there any experience of this? ED
PS A useful by-product of all of this has revealed that an engine undertray was never fitted - so one is now on order. "Project Drive" again:mad:??

Hi Edward,

Already replaced mine (with a Corteco one) and if anything the pulsing was worse with the new one.

Now is the rubber harder with the replacements than the original I wonder?

About to replace LH side engine mount (on top of gearbox) to see if that resolves it.

If you are in the area (near Woking, Surrey ) it would be good to compare the two cars!

I wish you luck in your quest gents...
My steering wheel vibrates so hard,specially when cold....i've replaced all 4 engine mounts (rimmers) Luk clutch kit + DMF and longlife ss exhaust system....Corteco pulley as well.
And guess what.....vibration still there.

You might consider finding someone with a T4 to check that all the injectors are working properly. I'm sure someone will correct me if I'm wrong, but I suspect that this could cause vibration at tickover, and it might cost less than replacing engine mounts - definitely less than replacing the lower pulley!
PS. If you add CDTI to your profile you won't have to put it in every post.

Thanks for the idea - but all 4 injectors have been refurbished by Alan at Lynx Diesels, then checked over on T4 by Phil-T4 and everything given a clean bill of health.

Maybe tweaking the idle speed a little would take it out of a band when something is resonating. - I wonder...

Every time something has been changed it has seemed a "little bit" better - but that may be purely psychological, but the underlying issue remains. It is not very bad, just annoying!

Steering damper?
 

Thanks for this. A MG Rover specilast garage has suggested I have a T4 intervention to alter the idle speed, but did not mention any possible problem with injectors? Maybe worth a try! Thanks for this and all the other inputs on this thread. ED

i think this kind of damper would cure wheel wobble in the axial plane when the car was moving, but from what i can assertain the wheel is vibrating laterally and horizontaly while stationary at idle.
This points more to movement of the engine, subframe and steering rack...

Vibration from the engine will pass through the driveshafts and can be transmitted through the hubs to the track rods and up the column.
This then begs the question, is the engine/gearbox mountings soft or is there play in the steering or suspension. Even sloppy front arm bushes could be the trouble as they are less likely to absorb vibration. Don't discount the fact that if fitted a steering damper could well be the problem.

Some of the diesels have an extra solid weight welded on the top linkage
which connects the drivers side Hydramount to the secondary rubber mount bolted to the inner wing. I assume it is some sort of harmonic
damper?
