i cant see from the pics what has actaully broken, but if its th einternals to the gripper than i would like to bet Tom Seal would like to have alook at it (Mr Gripper for those who dont know)
that does look like a small diff - what size is it btw ? and what power is your car ?

it wont be the actual unit thats broken it might be bits of the crown wheel or the pinion
personally after my experiance with Tom Seals i wouldn't give him my diff ever again to rebuild , he subs lets the diff it to Coventry Automotive for rebuild they gave me back the diff with no pinion seal and kept my spare 108mm input shafts , i still have not had them back
im sure they went into Nutters diff because his diff was there at the same time
him/they took the piss with it and still to this day he never gave me the plates i asked for my diff still has too much preload on the plates still grines around the corners at slowish speeds does my head in even worse when the oil get warm
they are a good diff tho
ps thoses phone pics are shite

marco,the crown wheel is undamaged,some of the bits are from the pinion,the main bits in the tin are from the gripper.it still drove,and i think the damage to the pinion was done driving back from brunters.is there a mullet diff available to take big power?i will ring tom on monday,and see what he says. ps,the pics where taken with my high quality aldi camera.

Hi Lloyd
ring Tom first see what he says as it his unit , if you have broke the gripper unit itself you are the first person i have ever heard of breaking a unit
see normaly with these gripper/atb/or vc diffs these never break it's normaly Crown wheel /pionion /planet gears (vc) that break first
with the Gripper plated diff sometimes the outer bevel plates can break but you wouldn't hear anything all you would lose is a bit of preload pressure
i havd had my 7.5 gripper plated diff for years never broke anything
have had the plates change and serviced
is yours a 7" diff still shouldn't matter tho
ps scrap that camara they are bad pics take a few more without the flash on so i can have a better look

hi lloyd
that looks pretty bad ,
did you buy this diff brand new ?
if not was it ever service ? still that should never happen
what i can understand is your car is 4wd you only have 70% of the power going to the back wheels
i would defo let Tom know anyway even if you dont chose too use him
this has got to be the first plated diff i have ever seen broken,might have been faulty part that has caused the damage
unlucky mate

i have dropped the pieces of the diff off for tom to look at tommorow, it doesnt look like many bits are salvagable.iam using the skyline box marco,most of the time its in rwd. looks like ive now got to find another plated rear diff,whats annoying is its now off the road again,
