Diff Fluid Change

[bfrank81]

I'm getting ready to swap the fluid in the front and rear diffs. What should the torque be on the bolts when I put the cover back?

Thanks!

I wish the damn things had drain plugs...

suction gun?

we have a diff fluid exchanger at work. sucks old fluid out, puts new fluid in, works off of air pressure.

Yes, I have used those before. But for the common man, why can't they just put a drain plug in? I know it's nice to remove the cover to check wear and stuff, but I bet fluids would get changed much more often if there was a drain. I know mine would...

Oh, that is a good idea! I have one I use to change boat oil. I will use that!

How do I know which one I have? Or is one the rear and the other the front...


As for the drain plug ohh yea it's nice. I had a Nissan Titan and it had a drain plugs in both axles and it was sweet. Swapping out the fluid was very easy.

dana 60 is the front axle, 10.5 is the rear (SRW)

Drill a hole in the cover.grind off paint, weld a nut on the outside then put a bolt in with a washer and some silicone. I did the same on my old chevy' for a filler also.

Yea, I considered doing that...
