i have this high pitched whine coming from the rear of my car, the faster i go, the louder it gets, if i coast its at a constent whine, but if i tap the gas it gets louder for the time being... ive searched and cant find anything to help me... please give me some imput its really loud and annoying, and i need to fix it

 

I know you said it's not, but it sounds like your gears to me. I'm guessing you still have the stock 10bolt with aftermarket 4.10's added?

 

start saving for rearend rebuild

 

no, i dont have the gears in yet, stock 10 bolt still...someone told me it could be my hub bearing?? im not sure, anyone else?

 

10 bolt style rears dont have hub bearings.
sounds like gears to me, bad bearings make a grinding noise.

 

sounds like the carrier bearings are worn like every other 10 bolt ive rebuilt.when the carrier bearings wear out it messes with the backlash on the ring and pinion.get yourself a master rebuild kit for when you do the gear swap.

 

Could be the outside axle bearing does it sound like its coming from one side have pulled out the drivers side on many of this 10 bolts and axle was pitted up badly where bearing rides causing noise.

 

Does the pitch change with speed ??

Id say it can either be a pinion or a carrier bearing. Carrier bearings normally are more of a growl, not a ring. Its either that, or your gearset is on the way out from the pre-load going away from a carrier bearing as stated above.

 

my vote goes for carrier bearings

 

how much do those run ( carrier bearings).. im just going to get new gears, what else would i need to fix this problem???

 

Just get a ring and pinion and deluxe install kit. The deluxe kits come with every new bearing and seal in the rear including axle bearings. They run about $120. If your not doing it yourself be prepared for at least $300 in labor to do the job though.

 

if your even the slightest bit mechanically inclined you can do it yourself. gears are easy.

 

if it changes when you let off and on the gas it's one of the pinion bearings. The
bigger one, closest to the pinion head takes all the load when you're on the gas.
More than likely that is your bad bearing making all the noise.
