My Messy Afternoon

I got very messy today.

 

 

I decided to check and drain/refill my front and rear differentials and my transfer case fluids.

I was glad I did.

 

I started out by degreasing and cleaning all around the drain plugs and filler plugs so i wouldnt get funk/dirt/mud/animal bits inside when I went to fill. That took awhile.

 

The level of oil in the rear was fine, the front was about an inch low.

The oil on both front and back that was drained out was rather dirty, good news was hardly no metal shavings on the magnets and a visual inspection inside with my mag light the gears did not appear to have hardly any build up on them. They were much prettier than when I replaced the differential on my brothers 78 celica a few years ago.

 

The transfer case fluid was also rather dirty, looked like it was starting to burn, and the case was only about half to 2/3 full at best. If I was to guess I would say I drained out only 1 quart of transmission fluid. Not good! Again very few metal shavings on the magnet so that was good at least. Glad I did it when I did.

 

After looking at the drain plugs, filler plugs and the seals on them, and factoring in all the other original parts on my truck (including many I have already replaced), I am 100% convinced that what I did today has never been done on my truck ever. :angry:

 

This makes me very much want to take on the A/T next weekend, mostly out of fear.

 

I dont know if it is my imagination or what, but it does seem to move more smoother now than before.

I've done both diffs, and the T-case once before, but I'm due again.......I'm not looking forward to it. Real messy job. Good on you for tackling it though. :aok:

Can I do Synthetic in the rea diff and regular in the front and tcase since the front is only being used intermittently? Unless I offroad a lot.

 

What would you fellas recommend as far as brand on the Synt oil? for the diff and tcase

If you can find someone who sells Amsoil, that's a terrific choice.

Personally, I would use synth in all areas, including both diffs, t-case, crankcase and trans. I would find some synthetic grease and pump all areas (where you can)full of the stuff. The extra cost will create peace of mind when it comes to extended drain intervals. You shouldn't even have to touch the diffs for another ten years (at normal usage).

 

I cannot stress more how well synthetic oils work. With all the talk of increased fuel economy, every manufacturer will be using more and more of the stuff in their cars. Less friction, less wear, better economy. Almost every domestic truck on the market today has synth somewhere in the drivetrain. It just makes plain good sense.
