I purchased a 94 LC recently and finally got around to draining and refilling the differentials and transfer case. I went with Amsoil Severe Gear 75W90.
Rear differential and transfer case old fluid was not bad. It was cloudy/smokey but not black.
The front differential was a whole different story. The old fluid was like black muddy water. It did not even look like gear oil. I'm afraid the differential itself was compromise by Birf lube/grease.
Has anyone had the issue where the front diff fluid was contaminated? What issues would I run into if my birf was going and leaking grease into my front differential?
BTW .. it's a 94 with only 83K miles
one more item ... there's a guard/shield that protects the drain plug on the transfer case. It's held on by 3 bolts. Only two bolts were there. The 3rd bolt was snapped off at the head. I snapped another bolt removing the shield. My question .. what's the best way to remove the snapped bolts? I assume I have to drill them out? If yes, what's the best type of drill bit to use? I want to eventually reinstall the shield but need to remove the 2 snapped bolts.
TIA
