I just changed the differential fluid for the first time. Put in some top quality synthetic and it shifts and runs way smoother.

I fail to see the correlation between the two. That's like me saying I changed my differential fluid and now I get better radio reception, lost 20 lbs and my teeth are whiter.

Not to mention that diff fluid plays no part in shifting...

I change the oil in my differentials, transfer case, and transmission around every 30k. If the axle tubes go underwater, I change the diff fluid. Same with the transfer case.

I usually use Mobil 1 synthetic gear oil, and just regular ATF+4 for the trans and transfer case.

So.. In summary... DO IT!

Changed the brake fluid and didn't notice anything.

Power steering, radiator and clutch fluid are next.]]> http://www.dslreports.com/forum/Re-Help-Change-oil-in-rear-diff-or-leave-alone-27728964 Wed, 14 Nov 2012 21:23:03 EDT Re: [Help] Change oil in rear diff or leave alone? http://www.dslreports.com/forum/Re-Help-Change-oil-in-rear-diff-or-leave-alone-27725921 said by Beezel:

If you change the rear diff oil make sure if it is a limited slip or posi trac, or locking rear end you put the friction additive in the oil.

Or just buy it with the LSD additive already in the gear oil...

Change it all. Front diff, transfer case and rear diff.

..and transmission fluid.

Also check the seals for leaks, or places water can enter the system if you were to go off road.

BTW, I did my rear diff on my Cherokee. 220k miles and oil did not look bad. I used synthetic blend, did not want to spend the $$ on the synthetic.

I just pulled the bed off of my 2000 Chevy pickup to change the fuel pump and low and behold there sat the pumpkin in plain sight for me too see.....209k miles on the oem fluid.

It was not nearly as nasty as I thought it would be.....Luckily I taped a magnet to the bottom when I bought the truck.....Lots of silver mud but no chunks!

Seems awful low. Most are 100k these days.

Since the rear is always used it wont make a difference if you dont use 4WD.

I would like to change the oil in the rear diff as a preventative measure, but is it really necessary to if you do not use 4WD often?

Also, what is the recommendation on changing the oil in your diffs?]]> http://www.dslreports.com/forum/Help-Change-oil-in-rear-diff-or-leave-alone-27721999 Tue, 13 Nov 2012 08:13:18 EDT
