Diff banging.

**Steve_S15** · 29-11-10, 15:02

I know 2way duffs tend to do this anyway buy mine has gotten considerably worse the last few days on full lock at slow speeds it bangs very loudly and throws the back of the car side to side. A mate of mine said it sounds the same as his did when his crown and pinion went, my diff knowledge is very limited so I'm not too sure what to do to fix it or make it less knocky? Any help appreciated.

possibly needs an oil change

I changed the oil about 2months ago, would it need one so soon again?

What oil did you use? Different oils have different viscosities. Mine was the same changed to silcolene diff oil and now its perfect

mine was exact same, got the proper oil and didn't make a diffenence, dunno the correct phrasing but where the shaft goes into the diff was moning about 3inches each way so got new diff alltogether!!

The only way you will really know whats going on inside the casing is to pull it apart and have a good look around to see can you figure out what the problem is.
