Ok I finally got the QA1 panhard bar installed, and the TA Performance girdled diff cover. I swear, every time I work on the truck it seems like “easy” stuff ends up with one challenge after another. Lol. Anyway, the passenger side bracket for the new panhard was unbelievably tight. I tried ratchet straps (2), many iterations of prybar action, scraped all the gunk off the inside of the brackets to make sure there was nothing preventing the bushing from sliding in..you name it.. I tried it! finally, I pulled it back out, and ended up machining off about 1/16” from the bolt sleeves, because no matter what I did, they kept getting hung up on the brackets, and are just about a 16th longer than the loop ends. After doing that, I greased the bushings, and was able to get the driver side in with the expected amount of prybar action. Back to the passenger side.. I ended up finally using my floor jack to push up on that one, with a 2x4, to avoid buggering up the paint. That got it within about 1/8”… next, I got my biggest prybar back out and was pushing the truck rear up so much (30x or
So) that it triggered my dash camera to turn on. Ha! but it would only move a tiny bit.. I’m now within 1/16” or less and it was soooo close.. I found a pair of needle nose pliers that fit inside the sleeve and were just big enough I thought.. hey, it’s tool steel.. should be pretty solid.? Hammered on that a few times, to bring the sleeve up to the bracket hole, and then I could finally get the bolt in. I honestly believe this job would have taken me no time at all if I just had a lift! After I got everything back together, it was time to pull the passenger side plug, so I could drain the extra 75-90 in it, since I had added 3 quarts from the Amsoil squeeze packs, and the diff is supposed to be full after something like 2.2 quarts. What I read said the passenger side plug should be the reference point of the full diff. You pull that plug, and it should drain to the bottom of that port. So got her off the Jack stand nice and level, crawled back under there for hopefully the last time, pulled that plug.. and.. nothing came out. Wtf.. stuck my pinky in the hole, and still couldn’t touch the fluid level. So I’m confused as ****. I added 3 full quarts, and it still seems low. If this TA Performance cover adds a bit of capacity, I haven’t seen it mentioned in the instructions, and even if so, how much could it be? I’m planning to get more Amsoil tomorrow hopefully somewhere locally, so I can finally drive her again. Just floored that it could need that much in the diff. Apologies for the novel, I feel like this install was just about a 300 page book. :okay2:
