Thanks 4 the replies so far !
The reason I'm asking is my latest project may have 2 have driveshafts fabricated - and therefore I need 2 know the optimum length of the driveshafts to enable full droop and compression on the suspension without buggering up the cv joints !
Steve - Running so low on your astra - r u having problems with it eating cv joints - I had this problem on my 16V Nova (U may remember it from a long time ago!!) - It would eat cv joints 4 fun - I replaced gearbox/steering rack(was running quickrack which allowed tighter turning circle)/front suspension leg/hub and driveshaft!
My only solution was to put a spacer (similar to a 5mm washer) on the outer cv joint before it goes through to hub/wheel bearing - and redrill the split pin hole on the threaded section.
In doing so - effectively the drive shaft was 5mm longer allowing the cv joints to operate in their correct region !!!
This is one of the reasons I originally started this thread - I didnt want to go through all that again on my latest project
Sorry to thread jump fellas.
I'm having trouble with the CV joint on my Astra
Its lowered 35mm
I've replaced both driveshafts for recon from Vaux
The O/S has been fine, but the N/S has been chaneged 3 times in 4 months. The grease pisses out of the boot under the clip...then the joint starts knocking after a while.
Whats the chance of this being due to the 35mm drop bearing in mind the O/S has been fine and the original shafts were fine with this drop to.
Its just Vaux are saying they won't replace the shaft under warrenty again as its against policy and the car is lowered making the parts wear quicker than normal
I've not had problems with it eating CVs or driveshafts.. the car was running something like a -110mm drop, which was great on a very very smooth surface but *nothing* else.
I've just recently changed the front suspension to Pilbeam legs, Bilstien inserts and a longer softer sprint.. the rears i've put in a standard-ish height tarmac spec spring. Also fitted PAS back on all in the hunt for a nicely rounded handling car..
I think Merling Motorsport supply special CV's and driveshafts made to lenght.. could be worth giving them a call???
