Rear wheels1/2" play bearing nut loose?

Drifting
Got the car on my friends lift today, removed the half shaft and the tire had the same play as before, So I tightened the wheel bearing and that fixed it, did the same on the other side. Everything under this car is new so why the bearings came loose is a mystery to me? Maybe being everything is new they never seated correct and after putting on some miles they loosened?? Anyway hope this did the trick and I will check tomorrow the other things you said being thew car is still there on the lift! Thanks for all the help every one !!!! YOU GUYS ARE THE BEST!
OP, please get an experienced person to check out your rear bearings prior to driving it .
You can do severe damage and even shear the spindle off if it gets too hot.

Yes, Removed the old one and replaced with new, and will have to do it again when I re torque it. The drivers wheel took a few good turns to tighten and the pass wheel only took a little when I did it. did not under stand the Bubba meaning?? Going there today to redo and ask for some help from other people.

It is possible I guess that the bearing races weren't fully seated on assy and whoever put the spindle together only tightened the nut enough to get the end play out of it then put the key in place. Then, the races could have seated and left you loose.
Being from New York, you're not supposed to know what a Bubba is. That's a southern term.

All kidding aside I have a problem with the rear bearings I am working on!

If the nuts had keys in them and there was no torque on the nut, everything in that spindle/bearing assy is suspect.

If the person who set the rear bearings up previously set them up for a "slip-fit", then that changes how everything is adjusted.
You need to determine what you have, and you need a GOOD mechanic who understands this bearing setup. You may wind up removing the trailing arms and having them re-done by someone who routinely does this work (Gary Ramadei, Bairs, Ikerds, Duntov Motors, VanSteel, etc).
We can try to help, but you may wind up calling and talking to one of these guys about exactly what you found and did, and then see what needs to be done from there. Most of us (self included) send this work out to one of the folks I mentioned above. It can be done at home with the right tools and knowledge, but most of us prefer to let the experts with the tools/knowledge perform this work. They also machine the rotors after the bearing/trailing arm setup to remove any rotor run-out. This is also critical for proper brake operation.

To quote Al Borland
I would expect that your car drove squirrelly on heavy acceleration and made strange noises on turns, entering driveways etc.
Do you have sidepipes that may have hidden the noise?
Someone should have pictures of cars that lost a quarter panel due to
a frozen rear bearing. It's ugly and dangerous if you lose control.

L. Once tightened to this bearing clearance, any further tightening will just serve to create problems/issues. This is for the OEM design setup.

Slip fit bearings change nothing in terms of clearances, or setup. Their downside is increased potential for failure in street service. Upside is ease of maintenance in racing environments.
I'd guess the OP either has failed bearings, or he will find that Bubba removed the spacer and shim.

Bearing clearances are determined by a shim and spacer that separate the inner bearing races. If those parts are present, the relative tightness of a tight spindle nut has virtually no effect on the bearing set up.
Only because I know what you meant...you typed it out incorrectly. The spacer and shim are used to set the width of the inner and outer bearings when tightened in relation to the races...to achieve the correct run-out. The spacer and shim have nothing to do with the inner bearing race...and not races...because there is a only one inner bearing race.
I AGREE that if the nut if tighter than the 90 lbs/ft specified in the manual...plus additional tightening of the nut to get the cotter pin to install...has nothing to do with the end result. I have done close to 100 of them over the years and never had my setting change when I tighten the nut.

I agree...I prefer press fit bearings and NOT slip fit.

Hopefully applying the correct torque will work...and when the run-out is checked...you are fine...but if you plan on breaking the spindle(s) down...it does require some tools for this...and do not just go in and have you and your friend begin beating on the end of the spindle.
Not meaning to throw a bad vibe on this situation...but as many of us know how IMPORTANT this issue is...and if it was not performed correctly...WHAT ELSE can be incorrect. If the car came into my shop...I would have to go over it with a "fine tooth comb"....ONLY BECAUSE this has occurred...and I have had to go back over a car because the people who did the car....just slapped it together.
