I was under my 93 yj today inspecting a bad rear driveshaft u joint and noticed that the transmission slides back and forth easier than it seems like it should,,, it's the part just above my poly transmission mount, I noticed that there are holes that seem like they would attach this to the transmission itself, should there be bolts there that maybe fell off? Hope this is clear enough
Ha, I went out and reached my phone above the skid plate to take a pic of it to show you what I'm talking about and think I answered my own question cause when I looked at the pic I saw a bolt jut hangin out.....
The red (now red and black) thing is obviously my poly trans mount... The question I had was if the black part above the red poly mount was supposed to bolt in to the trans itself, I guess that's the bolt that should be there eh? And maybe the extra shake caused my u joint to fail? Am I correct in this diagnosis? Thanks dudes
Yes and Yes...those are the bolts that should be in the tranny mount, and likely the tranny moving around could definitely cause the u-joint problem. When you put the bolts back in, I'd recommend using lock washers to keep it tight. It looks like there is only a flat washer currently.
Lock washer for sure. My AX5 has a stripped bolt hole and only has one bolt holding it to the poly mount, after the original 2 bolts fell out or got yanked out. FORTUNATELY whenever I go and buy bolts like this I won't buy anything less than a Grade 8.
A grade 8 and a lock washer are all that's keeping my tranny from moving side to side. I did happen to check it a couple months after I put it in, still tight
So I replaced those bolts with 8 grade and locking washers, now when I drive it I am getting this crazy and scary clunking sound ! What could this be? Im thinking that now that the transmission is more secured to the skid plate that the dying u joint is able to move more causing this clunking sound? Sounds like something's gonna explode!
The tranny mount itself is good, after market poly mount which is perfectly in tact, it was the part above it that screws in to the trans itself that the bolts fall outof! That is good now, the drive shaft u joints are the prob now! As long as its ready to go for the summer!
x-2, all the locktite in the world is not going to work if the threads are dirty. Take the whole bracket off and clean out the thread holes and clean the bolts, lock tite the bolts with red (that's if you don't want to remove them anytime soon)
