A d35 takes 1.75qt and if it has the factory trac-lok it gets 4oz of friction modifier.

 

 

Changed my diff fluid. Only about half a quart of water and gear lube came out lol

 

What's the normal oil pressure for a 4.0 in 70 degree weather

 

That makes me want to do mine, my diff was underwater for a few minutes a year ago...

 

Did mine the other day. It was light gray and very thick.

 

I need to but ive had so much other crap to deal with i haven't had a chance

 

Odered some extended rear bumps stops.

 

Mine reads about 40, depending on iow hard I run it.

 

With how many miles, which oil, which filter...? 70 degree weather - do you mean cold idle or are you measuring with the engine turned off? Hot idle is approx 210 degrees no matter where you are. Pressure is very subjective between engines anyway. My 4.0 with 330650 KM, some minor suspected sludge, Rotella 5W40 and M1-301 does approx 38 PSI hot idle and maybe 50 cold. With how accurate the dash gauge is your realistic expectations should be slightly above the middle when cold, and slightly below when hot. The only spec is a minimum of 13 PSI at hot idle and approx 10 psi per 1000 RPM

 

Idle right now is 10psi at 210 degrees 750rpm.
I just rebuilt the engine

 

Is your sending unit working properly? 10psi is not good at all.

 

yeah dat be borken

 

Found a stocker parked next to me when I came out from work. Took the obligatory picture.

 

Its 40psi right now at 210 and 2500rpm
