OK as i fix my rear brake problem i put on my rim & tighten them up (rear passenger side is on jackstands) but when they are complety tighten i noice the whole rim wobbles like something is loose on the rear end?? i jack the other side up to see if it wobbles/shake but its solid and dont move,so what could be my problem now?

I'm a little drunk so my response might be irrelevant. So if I'm reading this right, finger tight your lug nuts. Lower car from the jack stands. Progressively tighten the lug nuts in a star pattern to 76 ft/lbs.

yea you are drunk lol, tightening the lug nuts aint the problem,the rim is on the rotor tight, it seems like the rotor and all it moving with the rim, could it be a bushing??? i was looking at this link,could it be this that cousinf it to be loose and wobbly?? http://www.lexls.com/tutorials/suspe...abushings.html

check all the bushings, the upper ball joints, and of course, the hub (though unlikely that).

You are going to have to actually look for where the movement is coming from. Jack the back up and stick your head under the car either in front or on back of the wheel. Than wiggle the wheel violently and look for what joint is allowing the movement. That's your culprit. If nothing suspension related is moving and it seems isolated to just the wheel itself you have a bad wheel bearing. Youll find it you just have to look for it.

if you have to ask, I dont think you are going to find it, but your best answer was j2b4o

X2. j2b4o is dead on. You need to actually look and diagnose this one yourself. While you are looking, listen also. Maybe it has to do with your caliper that you're having so much trouble with.

thanks guys i had to ask everything still kinda new to me on this situation,ill see what i can come up with

LS400BOY

just went outside took the rim off and was moving the rotor and it seems like its moving with the rear end drivetrain? like a bearing had broke or went out??, it wiggles back n forth but dont go up n down, is there a diagram that breaks down the rear and shows seals/bearing goes into place??? i hate to tear it apart and dont know what im doing or loose track of where stuff goes,any help please would greatly appriciat it very much

LS400BOY

i want to tear it apart to see if it is the wheel bearing or not

Leaving the wheel on will give you more leverage. To have to look at all the suspension joints. Anything with a nut/bolt needs to be watched while you move the wheel. Follow everything that connects to the hub and see if there is movement at the body or the hub. None of the rear connections should move freely under the sort of pressure you are able to produce. The rear CV will move along with the hub because it's supposed to. What your looking for is what is allowing the movement. I seriously doubt that the diff is moving while you wiggle the wheel. Everything with rubber needs to be addressed. Search google if you want diagrams of how everything fits together.

well when i did the other side nothing moves or even wiggles?? when i did this side in question is moves with the rear driveshaft cuz its connected to where it wiggling, so it got to be the wheel bearing aint it?? does that make sense?? i havent worked on alot of lexus problems but a few chevrolets/cadillacs

UspeedLs

Yes it's your wheel bearing that is bad.

j2b4o

Did you look at all the suspension components and connections to check no joints are allowing movement? Does the hub move with the wheel?? If it does it's not the bearing.

will this help? this where your axle shaft fits into. ALSO see below for rear spindle.
