I have a torque wrench and didn't use it, haven't had any problems so far.

The concern is with (Over Torque) and to not deform the sheetmetal cover.
You should tighten the bolts in sequence as you would a valve cover or a wheel. Do not over tighten, you are just trying to compress the gasket enough to form a good seal. You can do this by feel, I use a small wrench so I can better judge equal force used on each bolt.

In sequence? There are only two plugs for filling and two for draining.

Actually, all of the plugs are there to keep the fluid from coming out (:

I didn't use a torque wrench either.

I am due to change diff fluid as well.

Did you guys drive around first to warm up the fluid before you dumped it? Will driving even warm up gear oil enough to make a difference?

Yes. I see no reason not to.

Dunno, but I don't see how it could hurt.

Fluid should be warm, warm fluid drains easier and holds particles and impuritities in suspension, allow to thoroughly drain and "flush"! (Just like motor oil), for first time removing drain/fill plugs, check to "see" if any threads are visible and write it down and re-tighten to approx same thread view vice a torque wrench. sometimes therre are places where a torque wrench doesn't fit or can't be pressured accurate. Think a 10 lb "bag of sugar or potatoes" when torqing and adjust, better a bit loose than tight!

'Boarder,

I was going to ask you if there were any special procedures for our silver Saharas since it has already been established they are the fastest and most capable... Well maybe not, but it sounds good.

I accidentally combined 75W-90 and 75W-140 in the rear axle.. is this ok? is there any downside to using 140 instead of 90?

You just have 75W-115 if they're the same product otherwise.

Don't forget to use teflon tape or pipe dope on the plug threads. I always use the teflon tape.

LOL! Thanks for the laugh

Mobil might consider doing a special "dirtyjpwrangler" blend. Best of both worlds..
