At the risk of opening Pandora’s box, May I ask what gear oil you would recommend for the rear end in my TR4A (solid axle)? I am running Mobil 1 75-140 and found some metal flakes on my magnetic filler plug after Pitt Race. Usually there are some whiskers, but the metal flakes are concerning. The rear end is a welded diff carrying a relatively new (3 seasons) 4.1 gear set. I have yet to pull the cover. Backlash seems “normal.” The rear end was set up by Quantum Mechanics whom I trust.<br>
What do you all run for oil (brand and viscosity) and what is your experience?<br>
Thanks and regards,<br>
Phil<br>
