Re: Binding noise from the rear (TJ '01)
 

TW:
From this and your other posts, it sounds as if "stiction" could be the
problem. Good excuse to change the fluid in any event. I don't know what
DC's recommendations are for the '01 but for the '03 Rubi they say to go to
the 75-140 synthetic for heavy usage such as trailer pulling. The DC
dealers up here (Canada - West Coast) carry it under the Chrysler - Jeep
brand (Chryco I think). Their mentioning of trailer pulling and heavy usage
tells me it will most likely have better hi-temp characteristics. With the
75 low end, it should flow better at low temps as well (don't know about the
range needed in NZ though).
Hope that helps, have a good holiday.

Given the choice (and considering the application ratings) I will always
go with the synthetic option in an automotive application.

Re: Binding noise from the rear (TJ '01)
 

Thanks Bob. I am leaning towards the 75-140 synthetic. Although
temperature rarely (never) goes below zero in Auckland and max in summer is
around 26/28C, I do a lot of highway driving some weeks of the year. One
of our clients is about 125 kms away (round trip 250 kms). Dealer is
closed today, I'll see if they are open tomorrow for some advice. I don't
pull any trailers at all. Just some steep hills and highway speeds. We
are heading towards winter.

I was just checking the www.mobil.co.nz website and they recommend three
Mobil 1 oils: Mobilube SHC 75W-90 / Mobilube SHC 80W-140 / Mobilube HD
75W-90 for a '01 Jeep Wrangler. I think I'll stick to Mobilube SHC 80W-140
and add the additive in the rear for LSD.

Hopefully this solves the issue before it becomes a big problem ($$$).

Thanks for all your help.
