dodgy diffs

[dans]

I have had my failing griff diff replaced with a brand new one, however it appears that the new ones supplied were not exactly new. Due to a shortage of suitable planet gears the manufacturer has been using the least worn ones to build up replacement diffs therefore my 'new' diff is in a worse state than the knackered one it replaced. All alleged information of course, but it might be a useful bit of info.....and btw Ted this is not a dealer bashing session, they have been great and turned a knackered griff into a total joy to drive again - just that they got landed with a load of shitty diffs, I opted to take the car and enjoy a whining summer rather than leave it until a working diff could be sourced and spend the next few months on the bus.....

Do you know what make of diff it was? Or failing that, what model/year car is it on?

dans, just had the same experience with mine (96) the only time it would make a noise was after a lengthy motorway bash, stop at the roundabout, pull away and it would make a horrible rubbing/graunching noise. Had it rebuilt and it is just the same but not as bad.

on a 96N griff 500, think it is a GKN unit - they ran out of gears allegedly so have started using the old ones!!!

Mine is just sick at low speed when the diff clutches are struggling to engage - sounds like the mechanic is still in there fixing the thing - and when at speed it whines alot.

Dan,

Glad you finally got it back, hope the bill was bearable.
My diff started to whine a bit, they can cure it a bit by some fliud addition I think. In the end I had a sports exhaust fitted, drowns the diff right out!

So you decided on a dash yet? How about going the whole hog and trying to make a Cerbera one fit??

I have sourced a red one from a 1980 Vauxhall Cavalier which I think will fit with a little persuasion - It seems that the switchgear is similar to that in a 1996 Griff so there should not be too much re-engineering needed.
