Title: Any opinions on GL-4?
Post by: aka-justin on October 07, 2010, 08:53:41 PM
Plan on running this GL-4 gear oil in my AX-5 (95 YJ), any comments?  Would there be any issues in a open-diff axle (D35)?

Thanks for your time.

This was the closes thing I could find that wasn't GL-5 at my Napa.  I guess I could try to take it back and order the MT-90.

It would be better to go with the tried and true in the AX5.  Penzzoil Synchromesh or Redline MT-90.  I wouldn't experiment too much with this, especially with Penzzoil Synchromesh being cheap and readily available.

Redline MT-90  is available for just over $10 per quart with free shipping (case price).

The penzoil is cheaper.  See Jeffy's oil study (FAQs?) for comparison.

Ok, i bit the bullet for some Redlin MT-90 for $12.50 a quart, 4 quarts worth.  I'll be putting it in my AX5 tomrrow.

I imagine the CRC 80W-90 GL-4 is ok for my rear dana 35?

For the rears, I use whichever 80W-90 is cheapest and change it often, as every time I get axle deep in water, I change out the oit (and that happens often around here).

Well, I flushed the tranny and was I shocked.  The oil looked like ivory paint or pancake batter.  Luckily I had some generic gear oil to flush it with before I put in the redline mt-90.  The second drain it only looked like honey mustard.

No more deep water for me.  Vent hose looked ok, but I think its a front seal.  I'll get it next time I have to mess with the clutch.

I've found that in my differentials a couple of times...  Never in the TC or tranny, though.
