rear end FIT!!!!

diff rebuild vs whole rear swap

rear end FIT!!!!

Postby abernathyadam [OP] » Dec 29 2011, 10:38am

This is my first time to post in a forum but I need help! I have a 2007 Silverado ex cab with the 4.8 V8 and I think it has the 3.23 rear with around 80,000 miles. Now I am in Afghanistan and my wife is having problems with the truck. It has been making noise from the rear end for a couple months now and the dealer told her it was normal and then she started to get vibrations and took it to a diff guy and he said the rear needed to be rebuilt and the bearings needed to be replaced. Now I am no gear head but I try to be informed. Her guy quoted her up to $4000 to get it all done. Just by looking around online I can't foresee why it would cost so much. Another question is if I go threw the rebuild would it be worth my while to change over to the 3.73. I have tires that are barely bigger than stock and I do a lot of towing would it make that big of a diff. Another thing is I have been looking and I can get complete rear ends from the junk yard for a good price. Is it cheaper/ better just to swap out the whole rear end. Thanks for any input.

$4000 is way to much and never go back there again. The side bearings should not cost more then $75 and it sounds like he is planning on a $3,000 labor bill. Does the truck have a G80? Those can make noise especially in tight turns and slow driving because the axle is trying to lock when it senses a rear wheel slipping as might have in a tight parking lot maneuver or making a "U" turn.

If its a 4x4 truck changing the ratio could get expensive because you also have to change the front axle and then re-program the powertrain control module to reflect the new ratio.

+1 Time to visit a different mechanic! While I try to see the best in people, it seems to me that this sleazebag is trying to take advantage of your wife.

Do you have any mechanically-inclined friends? Maybe you could have them take a listen to it. Like Z15 said, if it has a G80 locking rear diff, those can make noises that are normal, too.

abernathyadam I have a 1999 silverado that I just had to put a new rearend in.My spider gears were shot in mine and after about 2 weeks of looking around I found a complete rearend from a 2001 silverado for $250 dollars and did the swap myself.I found the rearend only about an hour away from me.Look on ebay for your rearend I found tons for my 3.73 rearend for around $800 I'm pretty sure you could do the same for your gear ratio. Also check any local junk yards you have. P.S. find a new mechanic because that price is outrageous.Good luck!!!

thanks, it is an open diff with no G80. My father-in-law is getting the specs together for me now and I have been spending the last several hours in contact with pick-a-part places around houston. Looks like it is going to be faster and cheaper to swap out the whole rear end sence I am not there to do the work myself. Now I just need to find the rearend I need. houston area/3.73 ratio or 3.23/ and a good price

I agree, just go with a used rear end. A rear end is one of the few parts I am comfortable with using that is not new or rebuilt. They usually will last the life of the vehicle. I would get one with the same gear ratio and just keep it stock.
