Anyone have any suggestions for a good fluid to replace the old F & R Diff fluid? I am pushing 20K and need to get that replaced.

 

BADodge,
I switched to Valvoline 75w90 Extreme Full Synthetic. It runs about $9 a quart from NAPA.

Running Mobil One full synthetic GL-5 75W-90 in mine. Front and rear.

No compalints.

 

Been running Redline 75w-90NS since 1700 miles, no problems, about to change it out at 20k, just bought more from a hook at the local supply, and was able to get it for $4 a qt, usually runs $7-$8 a qt though.

Also running Redline in the tranny (Redline MTL) and Tcase (Redline D4-ATF), quiet and smooth, will change it to at 20k.

Look up Redline's website www.redlineoil.com and read about it all, I think it is equal to the quality of Amsoil, which I would have used if I had a source locally, but there was none to be had.

Hey thanks for the input!

 

I run AMSOIL through out. Its 100% sythetic and works great. You get it on line and at GI Joes and anywhere you find someone that sells it.
