I installed a Rough Country 6 inch lift about a week ago in my brand new 2008 FJ. Included in the kit were new spindles, which I swapped over my stock wheel bearings and hardware. After driving the truck for about a week (less than 150 miles) I discovered that I have play in the front hubs I can move the tire/hub assembly about a 1/8".....

When re-assembling the front axle shaft I used an impact wrench to tighten the 35 mm axle nut, rather than getting my torque wrench and setting the nut to factory specs.

Now that I found play in the front hub, is it possible that I just need to tighten the axle nut tighter? or did I wipe the hub bearings?

The truck has a total of 500 miles on thr odometer... I installed the lift kit last week and drove less than 150 miles...

I guess I'm asking is it possible that it would be normal to have play in the front hub bearings if the axle nut wasn't torqued enough?

Did you have to press out the factory bearings in order to reuse them? If so that's probably your issue. Most sealed bearings don't take well to being removed and re-installed.

The wheel bearings on the FJ are not pressed in like the early Tacoma's. The wheel bearing and hub assembly have a flange with 4 bolts and bolt to the spindle.

I just took the stock spindle unbolted the hub and put it in the RC lift kit spindle.

Interesting...I would not think the axle nut would effect the bearings preload but I'd get the torque specs and check it to be sure.

check your bolts, make sure everything is tight, from wheelnuts to the 4 bolts holding in your bearings. i did lifts on a new tundra and a new tacoma, both same style and there were no problems like this. did use a torque wrench to get those axle nuts right, but i know my tech buddies just hammer them on with an impact and there never seems to be a problem.

is the movement side to side and up and down or only in 1 direction, cause maybe you're feeling something else, like loose steering or loose balll joints.

either way get a big torque wrench (over 200lbs i think for those axle nuts from what i remember) and go over all your front end stuff.....

When I jack the tire off the ground I have play in all directions of the hub. I can wobble the tire about an 1/8th to a quarter inch in any direction. I checked the four flange bolts that hold the bearing assembly to the spindle and they are tight as hell. The only bolt/nut in the front end that could be invovled is the CV axle hub bolt.

When I installed the new spindle/hub assembly I used an impact wrench and just tightened the axle nut as tight as the impact wrench coult turn the nut. It's my fault for not grabbing my torque wrench to make sure it didn't need to be tighter.

I'm NOT getting any play whatsoever in the ball joints. It's all in the hub section.

I'm going to tighten the axle nut until the play is gone and pray that I don't need new bearings...

Anyone know if the replacement bearings have the hub pressed into them? or will I have to press the old hub out of mine to put into the new bearings?

Did you put the cotter pin back in the axle?

Yes, the cotter pin and nut lock were installed.

I re-torqued the axle nut until all play was gone.... All is good! no noises, no play, and all problems solved!

did you check the torque on that big nut? using an impact gun to "torque" down nuts is never a great idea...usually never gets anywhere near tight enough ;)

I think they bearing and hub assembly are sold separately. About $300 per wheel, IIRC. I think the bearing alone was $160. Had my local Toyota specialist call Toyota Parts to find out how much new front bearings would cost just last week. And that was no mark up price.

Ya you buy the whole hub as an assembly. Off hand I believe the torque on the axle nut is 178ft-lbs. Your impact gun might not have gotten it torqued enough. Kinda depends on your settings and air pressure, but then again that's never a good way to torque a drive line component. Try hitting it with a torque wrench. If that doesn't work take a look at that hub.

Yup, I learned my lesson about using an impact wrench and not checking with a torque wrench. I jacked up the front end and rechecked the axle hub nuts and torqued to the factory spec 174 ft/lb..... haven't had any problems since. no noise, no wobbles, and absolutely no play.... I just hope I didn't put any premature wear on the bearings driving the 50 or so miles without the correct torque.
