Replacing a Rear Axle U Joint : Installing Mounting Bolts to a Drive Shaft
Replacing a Rear Axle U Joint : Installing Mounting Bolts to a Drive Shaft


In this clip we’re going to talk about the
proper service procedure for removing and replacing a rear axle u-joint on a ford explorer.
In this step we’re going to talk about the proper service procedure for installing your
drive shaft mounting bolts and the torquing procedure required in tightening them. What
I’m going to do now is start all of my drive shaft mounting bolts. You’re going to want
to start all of them before tightening any of them down just to make sure you can get
them all lined up, two here and two just like it on the top. Alright, take my three eighths socket wrench
with a twelve millimeter twelve point socket on it and go ahead and tighten them down.
There is a tightening procedure for these. What you’re going to want to do is do an “X”
pattern with it. You’re not going to want to go from here to here and then here and
here. What you’re going to want to do is go from here to the one diagonally across from
it. So it would be from here up to the one on top, from there you can drop straight down
to this one and then complete your “X” pattern by going over here to the other one on the
top. What that will do is ensure that your drive shaft is seated flat and true on the
pinion flange. These bolts are made of hardened grade A steel
and you’re going to want to go ahead and tighten them down just about as hard as you can. If your vehicle happens to be equipped with
smaller bolts, of course reduce the tension you apply to them. And now for the last one
in my torque sequence, complete my “X” pattern here. Alright, that is the proper torquing procedure
for reinstalling your drive shaft mounting bolts.

    you will know your u joints are bad if first you hear a knocking noise coming from the rear of your car when shifting and accelerating…if you hear this noise go under your car and try to shake your driveshaft and if there is play in the driveshaft it usually means ur u joints are shot…its a cheap fix if u do it by urself

    EV,  do I have to lube the yoke prior to reinserting it in to tranny?

    Also, when I remove my drive shaft, I did not index it.  What should I do before reinstalling?

    Thank you.

    eric i am a big fan. very informative and well explained. however if you recommend to mark the axis of the flange and U joints, why would you line them up in the video? also great advice on the torque sequence for flange! Greetings!!!
