    7 inch Pro Comp Stage 2 lift
    Okay guys, I just bought a 2014 Tundra with 25,000 miles. It already has a 7 inch Pro Comp Stage 2 lift, installed by a reputable shop.
    I noticed a couple days ago that the front diff has a slight leak. Doesn't really even drip on driveway but I don't like it. Thinking maybe shop either over torqued or under torqued case bolts. Hopefully case isn't cracked. I know Toyota ain't gonna fix it under warranty, so Im hoping the shop that did the install will. If not does anyone know how hard it would be to split cases and get new seal and fix myself? I know rear diff would be no problem, just never messed with front.

    I forgot to mention there are 5 bolts that attach Pro Comp cross member diff bracket to differential. You have to take OE bolts out, attach bracket and replace bolts.

    Oh yeah. At first I thought it was motor oil, but definitely has that nasty gear oil smell. Seeping out of differential.

    I pulled out my front diff clamshell on my Tacoma with 6" drop bracket lift. It was a pain in the ass to find the right position to drop it out. The drop bracket gets in the way. @Sean266 was there helping that day. Not sure on a tundra though but assume it's similar just a bit bigger diff.

    Figured out what it is. Shop that installed lift reused two factory bolts that were too short. Should have used replacements supplied with lift. Were no threads at all grabbing. Got two new ones and will be putting them in shortly. Hopefully that does the trick.

    That is a goof. The kit should have come with longer ones if a new bracket is bolted in place.
