Diff Clunk

[timbo]

Lot's of issues this week!

Searched forum and google but couldn't find what was happening to me.

So after fixing the starter motor and exhaust manifold gasket I took the car for a drive only to discover a very loud and violent clunk through gear changes and hard acceleration or dropping the accelerator off abruptly.

I double checked the trailing arms, sway bar, shock mounts etc and they're all tight, so I guess its the diff itself. After a short highway drive the diff was too hot to touch, could it just be low on oil?

sounds like lash in the diff, but yes check oil

yeh def sounds like the backlash needs adjusting. if you can just take off the nose cone from the diff (means you have to take the axels and shit off to do so) and take it to a gearbox or diff shop. will only take them 2 secs to fix

righto, well ill try some oil first seeing as thats easier then getting the diff out and if that fails, off to the diff shop!

make sure the car is level when you fill it through the fill hole man!

haha yeah cheers mate! any oil recommendations? i was thinking about penrite lim slip 140.

[blair]

thats what i use. the blue shit. It's thick lol and smells like week old unwashed banus.

cool beans, how much? im guessing i'll need 2 litres?

[blair]

Yeh, takes about 1.5 fromt memory.

Not sure about price, i got 2 x 1L bottles for a few pennies with my $500+ diff re-condition lol.

well got some diff oil, ended up with 90 repco stuff which is actuall made by penrite... only $14 so why the fuck not? diff is awesome! only a litre came out and over 1.5 went in.

clunk was still there...

had a closer look. broken top trailing arm! whiteline adjustable... sad panda.
