Zuk,
They are the gears that you helped me through the setup. Yukon v6 4.88's. The pinion preload was 9 in/lbs. I just figured they should be broken in by now. The housing is still very hot to touch. You can leave your hand on it but it's very hot. I put some valvoline synthentic blend stuff in there that I had laying around the shop after about 200 miles. I'm planning to put redline in it once it's completely broke in. I guess the thicker oil can't hurt? Does it normally take this long for the temps to break the gears in to where the run at a somewhat normal temp?

85 SR5 4runner....Too many hours of work put into it, Hacked, Beaten, and Still running after all I've put it through

87 Turbo Pickup...Bought Her for $500 put another $500 in her and she's running like a dream.
