Looking for clarification on the bushing part number for the one that connects the two lower control arms (the lateral to the curved arm). I have Lemforder part nos 2978301 for the large front bushing, 2978401 for the large rear hydro bushing. Lemforder seems to indicate 2978501 is for the control arm, but it actually looks like the one that anchors the sway link to the control arm. Nothing offered matches the spherical type joint that links the two arm. See the following pictures:

Lemforder 2978501:


Curved lower control arm with unknown bushing p/n:


Lower lateral control arm:



Can anyone verify if the 2978501 is for the sway bar, and possibly share what the correct one is for the lateral-to-curved link? I don't think mine is bad, as the boots are in perfect condition, but would like to know for reference. I am replacing the large front bushings due to a brake shudder.

Thanks,

Edit: these are the 3 bushings the ZF catalog offers:

 

It is indeed the sway bar Bush.




It was my understanding that the smaller Bush on the curved front lateral arms was not replaceable. The larger one is, I replaced mine with the Lemforder part from rock auto.

 

Thank you for confirming that one is the sway bushing. Yeah, I stumled across another thread (https://www.jaguarforums.com/forum/x...71/#post854721) on that spherical joint. The good news is mine has no tears in the boot, and I think that joint has very minimal movement so it should last a while.

What did you use to push the front bushing in? Can it be done with a flat plate? Or do I need to find a pipe or adapter to fit the diameter? The photos look like the bushing edge is chamfered, so not sure how that would get pressed.

 

Unfortunately I was not the one who replaced it, so I can not attest to how it was done.

:-(

Frasser Mitchell will know I would bet, he has given me a bunch of hand tips. Might want to send him a PM.

 

Pushing in a new bush requires a steady pressure all round the circumference of the outer steel body. So a flat plate can be used but needs a hole in it for the middle part to stick through, because you mustn't push this at all. Any shop doing this on a regular basis will have made up some mandrels to push out the old bushes and push in the new. The old ones need accuracy of mandrel so the bush is pressed out without damaging the aluminium of the wishbone arm.

It helps to get the wishbone arm warm or even hot to boiling point so it expands and releases its grip on the bush. A couple of kettles of boiling water will do the job. Best to set it all up first ready to press before doing the hot water trick ! BTW this hot water trick only works because the arms are aluminium and expand far more than the steel of the bush housing.

It needs saying that great care is needed when replacing these bushes because the aluminium arms are less tolerant of damage than forged steel arms. You don't want to create a site for a crack to start propogating!
