will a long journey kill my already whining rear diff?

reason i ask is i have just found out i may be driving to lemans (1000 mile round trip-ish) and my rear diff (i hope) is whining when you let off the throttle.

how much should i budget for

a) second hand diff?
b) refurbished diff?

also how much work/labour is involved in swapping it?

cheers muchly

 

It would probably be ok but if you can then change it to stop any worries you have.

Expect to pay 150-250 for a used diff.

Speak to Marco Polo if you want it rebuilding as iirc he can get them repaired and uprated if required

 

whats the costs involved with buying a rebuilt diff then?

 

I have no idea mate.

I have Ł475 stuck in my head for some reason but I think that was what a gearbox cost me to get fixed.

PM Marco as he would know

 

id bring a spare diff from a back disk brakes sierra Ł50 and change it if it goes. actually no that,d be a bit heavy to bring with ya.. get it rebuilt

 

will pm marco now
