ZT-T 190 Inner CV Joint

Dubya · 4th December 2020, 12:41

Does anyone here know where I can buy a new inner CV joint for my 190? I reckon I knackered mine when I removed it during my clutch replacement (yanking on the driveshaft without success, eventually removed it from the gearbox by prising it out). Now I have terrible vibration and knocking approaching 50mph and turning left. Because of these symptoms I replaced the N/S outer CV joint (there was some play in it), however the problem still persists.
While replacing the outer joint I found there was a lot of movement from the inner, probably 2-3 inches which doesn't seem normal to me, could I have simply dislodged a retaining ring / circlip?

Any advice would be gratefully appreciated, thanks!

It's called a tri-pod joint because of the three bearing arrangement inside it.

To get the amount of play you have you must have broken the outer shell on one of the bearings when you were hitting it.

You definitely need a new unit or maybe to a car breakers with a R75 being broken.

I guess the tri-pod joint is longer lasting than the outer constant velocity joint, probably due to the fact it doesn't have to move through as extreme angles as the CV. I was reluctant to get a s/h unit for fear of not knowing it's condition. However, they probably won't be as bad as mine currently!

Second hand, probably OK. As you say there's not much movement when it's working.

I've heard of the outer unit needing to be changed but not the inner.
