i have progressive grinding noise n the rear end of my sc300. at first i thought it was the breaks, but when i apply the brakes, the grinding does not go away. could it maybe be the hub bearings or something else??

 

ur end might be done. same thing happened to me. then it just got wrost and wrost. now i wont drive it. i suggest check the fluid for metal shavings.

 

check my rear end fluid?? HOW???

 

when i turn to the left the grinding gets slower, and when i turn to the right it gets faster. and rear brakes used to squeak, but they dont anymore. i am getting them replaced, but could it maybe be a broken brake pad, or maybe the e brake shoes??

 

i can also feel the pulse in the brake pedal

 

Sounds like you might have run the metal backing of the pads into the rotors. The squeeling was the little metal squeelers on the pads telling you to have the brakes checked,That usually starts when there is around 2/32 of pad left. If you ignore that sound for too long eventually all of the friction material (most often on the inboard pad that can't be seen through the wheel) will wear down and it's bad news from there. You're probably gonna end up buying new rotors as well. It won't matter if you're on the brake pedal or not. at this point they are gonna rub non stop.

 

i pulled the rear wheels off and the passenger rear wheel and rotor wiggle a half inch. when i wiggle the wheel i can see the rotor move to. thats what is grinding, but what could be loose, is the rotor shot?? can anyone help??

 

try and wiggle your wheel with everyhing on there... try holding 12 and 6 position and wiggle it... if it moves then you have bad bearings... when you check front wheels same 12 and 6 will tell you the bearing condition and 9 and 3 if it shakes a lot then something is wrong with your rack and pinion... you said you have different noise when you turn left and right ... sounds like you have problem on your hub area... and when the wheel is on you jack it up and you wiggle it. on normal condition it shouldn't move at all... on any cars... if it moves something is wrong ... well try that first... and if you have any question you can either pm me. i hope this will help...

 

yeah i'm pretty sure its the bearings, has anyone replaced them themselves, or got an estimate of what a mechanic might charge?? Please help

 

if you take out the hub and take it to any mechanic it will be cheap and fast... i never done it on sc before but you might need press to fit that bearing in there ... or it will be PITA to make it go in there perfect... if you take the whole car to a mechanic it will cost quite a lot.... i guess like 2~300 maybe im not really sure on price... i never estimated lexus suspension work when i used to work as a mechanic...
