I just bought a 1990 2 door Xj, and im having to do a brake job on it. But i was wondering if i should replace the front wheel bearings. The PO didnt do much to keep the jeep running. When im rolling down the street i can hear a squeaking coming from the front left tire. Ive never owned a 4x4 vehicle and i dont know what things to expect when doing a brake job? any advice would be greatly appreciated.

 

pry a ujoint, wheel bearings are more of a grinding noise.
Shouldnt be loose at all or sound like this

Haha sad part is my do sound like that, this jeep was beat to Sh** when i got it. but cant complain for 1000$ ride,





It already has a 2in Rough Country lift on it.

ive replaced the valve cover gasket (cheapy cork one)
cleaned the Throttle Body and related sensors





How hard would it be to replace a u-joint?

And right now i have to fix the Vac system because it wont engage the front axle right now. I was going to do the mod with a Tractor PTO cable and see if it fixes it



the vac lines werent connected when i bought it, ive sense re attached them. but still no luck.

 

Thats pry your squeak then.
Ujoints can be a PITA if theyre rusted. If not rusted, theyre not too bad.
BFH, 2 big sockets, and a little time.

You could always do the free cad fix.
I think the ujoint replacement is in the writeups, along with my CAD writeup.

 

Ok thanks ill go search for them, Ive been kinda lurking on this forum so much good info but dont wanna ask stupid questions
