Weird problem.

So I was going down the road the other day, not giving it loads and I heard a slight bang and what I thought was me running over something.
Turns out something has fallen off. I think.
Haven't had chance to chuck it on the ramp yet.
The symptoms are like a clutch slipping but I'm sure it's not.
It's like one wheel isn't getting any power. I think it's one of the rear wheels as when I give it a boot full it seems so go slightly sideways.
To me it feels like a a cv has dropped out or something.
Had a quick look under and nothing seems to be hanging off.


Any thoughts as to what it could be?
Many thanks in advance.

Iv just read that back to my self and it sounds very vague but it's a vague problem ha.

I would suggest jacking the rear up and turning one wheel the other should also move ....i think it moves in the opposite direction .... thats if it defo feels like the rear you could of chuffed the rear diff fella ...

They common for going?

Everything is common for going lol ...its normaly just a process of elimination to be honest you got to remember these cars are quite old now ...if you feel its from the back end then i would start there ...

if its kicking rear end out it could be the diff has failed
you really need to carry out a few tests and have a good look underneath it on a lift as could be a few probs
