I have a leak at my right rear differential. I need the seal and have been searching all over the internet and can't find the seal. Does anyone use this differential so I can cross reference this ?

 

If it is the shaft (so not the diff housing and the large aluminum round piece where the shaft goes in) you might need part JLM20451. Hope his helps

 

Yes, it's leaking around that big aluminum spider nut. Thanks I'll check it out.

 

I tried searched all over the web and couldn't find it anywhere. is there another number ?

 

avos's part number is correct, go to Gaudin Jaguar's website HERE, you'll be able to type in the part number, even old part numbers show superceded and current ones...that website is a great reference for this and budgeting for parts orders. Click the order button, as this is one of two Jaguar Dealers we have as forum sponsors, so its like helping yourself in an indirect way.
