A further update - ours got waggly as I noted previously. Now re-greased and it's smooth again.

I'm wondering now whether ours ever actually needed replacing. Perhaps the original waggle was just a lack of grease. Worth a try for anyone else with the same issue.

Unfortunately the garage didn't renew the boot - it did get a new one when originally replaced though. I'm thinking that either the new one is split or it's not being sealed on properly. We'll see...
 
Hi S130- Have you any thoughts of what I wrote in #67 . Regarding the 2.2 being a different assembly around the "tulip" and that it could be Fiat and the diesels Vauxcrap?

Sorry to tarquin. I see I never responded to this post.

I've looked at the parts slides and the assemblies are totally different between the 1.9 and 2.2 engines.

It is difficult to say if the 2.2 shaft is a Fiat design or not. 2.2 is GM petrol engine and the gearbox is a Getrag F32 ([ame]http://en.wikipedia.org/wiki/Getrag_F23_transmission[/ame]) which is German and mainly fitted to GM cars.

All very confusing :(

If this doesn`t prove that the grease is the X factor in the whole 40 wobble saga you have now proved it beyond all doubt to me.
I have also just been thinking of why the amount of grease is specified by Fiat.
If you are putting a new gaiter on the Tulip then you have to take the spider off to fit the small end of the gaiter onto the shaft. If you were unaware of the specified amount you wold naturally just stuff the gaiter full of grease and slide the spider bck into the tulip and stuff some more grease in the open end of the tulip behind the spider.When the gaiter is the secured over the open end of the tulip you have a "sealed chamber" effect and movement of the spider inside the Tulip during cornering will lead to a build up of pressure inside the gaiter , rather like a n old bicycle pump when you hold your finger over the outlet ( yes I am so old:eek:).
If the grease is pressurised in this manner it will find a way of escaping , there will also be some centrifugal force thrown into the mix as well so its obvious to my mind how easy it is for the grease to get out.
