Plymouthy Adams Posted May 24, 2016 Report Share Posted May 24, 2016 the very chart in the lubrication section of your manual is still current and so are the fluids still available. Quote Link to comment Share on other sites More sharing options...
mopar_earl Posted May 24, 2016 Report Share Posted May 24, 2016 Straight weight is hard to find or no longer made. I used 80w-90 in my rear diff. Believe my car called for straight 80 and straight 90 depending on the season. Good luck finding straight weight gear lube. I use off the shelf Valvoline conventional 80w-90.

T120 Posted May 24, 2016 Report Share Posted May 24, 2016 I bought GL1 SAE90 gear oil at NAPA in the US - for use in the transmission...Use an Extreme pressure hypoid gear lubricant in the rear differential as in the manual, (available everywhere).
