Well I passed my sva today and the drive down to chelmsford was fantastic but judging by the very loud rumbling noises coming from the transmission and the rather large ammounts of driveline shunt I've broken something (damn 1st gear is so much fun). I couldn't really hear anything during acceleration (but got the feeling it was still there) but there was a very pronounced rumble during the overrun from high revs that could be felt throught the car, it dissapeared when the clutch was depressed at speed.

Its a kit car with cossie engine (running in at the moment )


I've checked all the bolts are tight, Its a XR4x4 7" LSD (3.62) diff, driveshafts, hubs etc. Gearbox has had a full rebuild by CTS less than 50 miles ago.

There is a lot of play between the propshaft and the wheels, although on closer inspection most of it is in the inner cv joints. How much play should these have? The diff input to output shafts play is a mm or 2 (around circumference of the input flange) the rest of the cm or so of play seems to be the cv's. There is a little play between the two wheels, but the lsd mechanism seems to be working ok

The shafts also move latteraly in the joints a fair bit, but i guess thats normal. The suspension was on full droop when I checked the play.

Any comments or ideas? Wheres the best place to get new cv's and how much are they going to cost?
