ok, i dont get it, i thought it was the clutch but im thinking its the diff
basicly,i put my foot down and the revs just shoot up without the wheels, i though it was the clutch but i jacked the car up to fit my new brakes and i start the engine and the front left wheel spins while the front right says still, put the clutch in and it stops, also (still on jacks) i put in first without touching the clutch, laft wheel is still moving without the right. im out of idea so any help will , i no the wheels move anyway but i was a bit concerned when the other wheels didn't move.
...and its a mk5b ford escort.

 

cos you HAVEN'T got a lsd gear box that's why one wheel spins and the other DOESN'T!

sounds like the clutch is knackered to me

 

lol, very true, blond momant! hopfully my clutch is still on warrrenty

 

if you drive the car put your foot down and the revs are going up,and the cars not speeding up,its defo the clutch.
