How to Replace Front Differential GMC Yukon Chevy Tahoe Suburban Avalanche GM GMC Truck SUV

Автокөліктер мен көлік құралдары

In this video, I show how I replaced the front differential in this 2011 GMC Yukon. This truck has around 110,000 miles, and had a loud whining noise coming from the front differential when the transmission was set to "auto" mode. Setting it to "2wd" would make the drivetrain whine go away. This problem happened because it was kept in "auto" mode its entire life. If the truck was kept in "2wd" mode instead, the front differential likely would not have worn out. So after this repair, it will be kept in "2wd" and only switched to "auto" when the road conditions deem it necessary.
This procedure is likely very similar for many GMC and Chevy Trucks, Tahoe, Suburban, Denali, Avalanche, Escalade, Silverado and Sierra.

    Thank you! I didn’t replace the bearings or seals. I just heaved the whole thing in and drove it. That being said, it may be smart to do bearings and seals as long as you know that the diff itself is in good shape. It would suck to put bearings and seals in and then find out the replacement diff is junk.

    Great video. I have an 07 avalance that was doing the same whirring noise when I left off the gas, got up to certain speeds. Mechanic told me put in 2wd. I just changed the fluid, it's better but the noise is still present. My questions are 1. is a junk yard dif worth it 2.would leaving it in 2wd cause also cause quick deterioration like being kept on auto 3. Why would leaving on auto cause the front to just go bad, not the back as well? 4. Could you fill the new dif up with fluid before mounting? Seeing how much of a pain it is to fill? Thanks in advance!

    Did you have to put the vehicle in neutral to remove the front driveshaft from the front diff? Also, did you spin the cv axles as you were loosening the 6 bolts on their flanges?

    Dealer says there's PLAY in my front dif. Truck drives fine tho. Can I go forward with underneath rust remediation and spray before fixing front dif?

  • @WiringRescue

    @WiringRescue

    2 жыл бұрын

    Well, it depends. If the front diff isn’t making a bunch of noise now, it could start soon, or maybe it won’t. If you are paying someone to fix it, you may want to get an estimate to fix it just in case it’s more than the truck is worth (depends on the trucks condition and if you are getting a new vs. used diff). If the repair is an acceptable price, go ahead and have the rust situation done. If the repair is going to outweigh the value of the truck, rust repair would be a bad investment.

    It has a different gear ratio. The external housing can be the same, but with different gears on the inside. You’ll have to swap yours over, or get a different front differential altogether. Sorry about the bad news. That’s a bummer.

    Honestly I’m not sure. You would probably need to keep the axle ends going through the hubs. So you make need to take the axles apart. But it seems somewhat doable to me.

    The video is about swapping a front differential, and I’m telling people what size the heads of the bolts are so they know what sockets they need. I am not talking about the stud sizes because those don’t matter for this job. Vernier calipers have no use in a front diff swap.
