really hot diff??!?!??

[vibrating_Cake]

had a trip down to doncaster (bwt 30-40mins) and while it was up on the ramps down there we noticed that the diff was really hot to touch, is this normal? was a good 30-40mins at~70mph with a couple of blasts well above that (on private land of course )

also the diff whines on engine braking, so if i sit it in 5th going down a hill on the motorway itll whine constantly till i put a bit of power back on then itll shut up....

 

is this normal or a sign something is wrong?

What's the oil like in it? could just need topping up!

 

A bloke in kwik-fit once told me to cut some old tights up into strips & to stuff them in the diff... they work there way around the cogs & quieten it

Sounds like the kind of trick that Boycey or Athur Daley would use to try and flog a dodgy motor.

 

Doesn't sound normal to get that hot for a normal pace short drive, nor does it sound good if it's whining on the overrun. As Stu said, check the oil level.

My LSD diff in my old escort used to get REALLY hot like that mate, just make sure that the oil level is ok and i wouldnt worry about it.

i love the whine of an lsd coming off throttle in 4th or 5th just driving slowly through the village roads

I wouldnt worry about heat. they have a lot of work to do. Id worry about noises though. check your oil level.

as long as it has the correct oil and the correct amount of it hot is fine mate our race boxes get well hot the oil is above 100 degrees C i think
