Rear Differential leak at fill plug

[xterror04]

Well its been a while but i have been noticing the fill plug on the rear differential is always wet... its leaking oil very small amounts though... Im just wondering if this is common or should I have put some sort of sealant on the threads?

Im guessing you have checked the tightness.. May be a good item to have trail spare of too...

Yea the manual tranny and differential plugs on Nissans are usually NPT threads so they need sealant on them

 

[drbandkgb]

hmm.. Never have added it.. Luke Im sure bashing the diff on rocks doesnt help either lol

 

[xterror04]

no it really didn't.. changed the oil today and added sealant... now running royal purple in the rear diff.. that was spendy

 

[drbandkgb]

I bet..

 

[xterror04]

i just am hoping it was worth it lol... need to do the tranny this weekend

I have always used cheap Teflon thread tape. Cleaner.

I always have teflon tape in my utility box (rear cargo area box). Had to use it on my old oil cap.
