i think my rear end is going out, or at least something in my rear end. the weird "whining like" noise is coming from the rear of my car and no its not my walbro i know what that sounds like......i had my freinds dad ride with me, hes a mechanic and does all his own work plus he drives a 2005 srt-10 thats over 700hp...anyways he rode with me and says it sounds like a bearing in the rear....has anyone had this problem or know what it could be.....any suggestions or comments

 

Are you sure it's the rear? when does the whine start? at what RPM, at what boost? need mods/driving style/etc... to be able to help. You need someone familiar with the AWD system, to help a bit better. all the RWD cars have problems in the "rear".

 

im pretty positive its the rear, ifs its not then its dead center of the car....this is under normal driving at any speed and any rpm above 1500....not even under any boost....its really hard to explain i mean it doesnt feel like im losing power but its just annoying and i know something is wrong

 

Did you check the fluid levels in you gearboxes? Take it to a good shop and see what they say about it.

 

when i come to a stop at a light or stop sign you can hear it whine down, and it couldnt be the t-case...it couldnt be, the noise is coming from the rear

 

Check fluids, and check the "center carrier bearing". I hear the driveshaft hit under the car in the "tunnel", it isn't a whine though. the only whine I got, was when the TC went out. I would first change the fluid in the diffs, and see if it is still there.

 

Try to have someone outside the car, and you drive by them, and let them tell you which end it is coming from. It could be the rear diff, but I haven't heard of many or any of them going bad. Have you put on any recent mods? last time changed the fluids? did you get this car new?

 

where is the center carrier bearing located

 

basic bolt ons, cams, gears, full exhaust, 10.5 housing flashed fuel pump....i had my friend listen as we were going down the road with his head out the window and he agrees its coming from the back half, yes i got the car new, now has 45k front fluids are ok i knwo for a fact i just got a new clutch and t-case

 

It is I believe between the front seats, under the car. If you jack the car up, and lay under the drive shaft, and push up on it, like you were bench pressing the car, you should not have Much play in the bearing. I had 1/2 inch of play between the bracket and the bolts on the center carrier bearing. (it is a round bearing, you cant miss it, it sorrounds the driveshaft).

 

ok ill check it our right now and get back to you....so how much play is too much or there should be no play in it?

 

very little play, to much play = vibration... vibration is bad

 

+1. I had TOO much play. center carrier bearings are 61.00, so it's not that bad.

 

did you change the carrier bearing yourself

 

No, I have my dealership do the work, I can see what that would entail. I actually tightened the bolts holding the center bearing, and the problem is now GONE, so I don't think i need to replace them now, but might anyway to add some "insurance". or is it assurance?
