Perfect. 2004 Tahoe with push-button 4WD (with large round AUTO button).

Excellent quality seal. Just like OEM. Took me about 15 minutes to change it. Just had to set the e-brake, put the vehicle in neutral to make sure there was no load on the driveshaft, remove the driveshaft by removing the 4 bolts from the u-joint straps and slide the driveshaft out of the transfer case, and then, using a large flat-blade screwdriver and a hammer, knock out the old seal by tapping on the flange in alternating spots to work it out of the housing. I expected to get some fluid out when the driveshaft was removed and the seal was pried out, but I got almost none. I know the transfer case is full because I just changed the fluid and I can touch it through the fill hole, so I guess it naturally sits below the level of the drive shaft, which is nice. The seal has a rubberized coating on the outer mating surface, so no sealant is required during installation. I just coated everything with AutoTrak fluid and carefully tapped the new seal into place. You can use a seal driver, but I had no problems just alternating back and forth with a large punch and hammer to gently tap it until it was fully seated all the way around. Then, you just slide the driveshaft carefully into the transfer case, rotate it to line up the u-joint, and then bolt it back on. Should literally take no more than 30 minutes for someone with even a basic amount of mechanical skill.

Good on 2001 Tahoe

Good product, received in perfect shape, as good as OEM or better. Install is easy, back out the four bolts at the rear U-joint for the driveshaft, carefully pry the shaft forward to dislodge from rear joint, then withdraw the shaft from the transfer case by pulling toward the back of the vehicle. A flat head screwdriver and mallet will be needed to tap the old seal out of the transfer case. Lubricate the inner and outer circumference of the new seal on the side that goes in the transfer case, as well as the inner circumference of the side facing out. Use transfer case fluid, such as the Auto-Trak OEM stuff from ACDelco. Square the new seal in the transfer case and push in as far as possible by hand. Use a small drift punch and work your way around the circumference until flush against the case. Replace the driveshaft with the reverse instructions from above.

Great Seal!

Even with the abuse it incurred from my improper installation (with a flat-head screwdriver and hammer used around its perimeter), the seal does a better job of preventing the transfer case leaking Autotrak than the seal it replaced. Highly recommended, especially if you install it with the proper seal/race installer!

Great!

Very good material. Seals properly!

Oil leak

Fit was good stoped the leak

Transfer case output shaft/slipyoke seal

Just replaced this seal along with a new slipyoke on my 2000 Sierra 4wd about 3 months ago. No leaks! Install was a breeze too!

Quality product at a good price.

Easy to install. Worked perfectly on my 2002 Tahoe.

Five Stars

So far it doesn't leak and less expensive than the parts store.
