I have never checked the rear-end grease which should be
changed and/or checked every 50,000 miles so it was time to do a complete
cleaning and change over to a deeper cover.
I took it to a qualified local shop H&H Diesel
Performance in Ottawa Kansas to handle this job because it was a mess back
there and needed a very thorough cleaning. I also installed a deeper rear
differential cover from BD Diesel Performance which provides extra grease for
the gears to pickup in order to keep it cooler.
The cover not only is
constructed better than the OEM cover with cooling fins but comes with magnetic
drain plug for easier fill up or changing the grease.
H&H Diesel Performance did a great job of cleaning out
the old gunk and installed Amsoil Severe Gear 75-140w. AMSOIL Severe Gear®
Synthetic Extreme Pressure (EP) Gear Lube is a premium-grade gear oil
specifically engineered for maximum performance in severe-duty applications.
I didn't ask how long it took H&H to clean that rear-end out but I got some dirty looks from their mechanics and after looking at the photos I can understand why?
This state-of-the-art AMSOIL formulation features an exclusive blend of
high-viscosity, shear-stable synthetic base oils and an extra treatment of
high-performance additives so it provides long-lasting protection against
metal-to-metal contact.
Only the best for the old 1996 Dodge Ram which does travel
to a lot of the DIESEL Motorsports events from state to state.
