2014 Terrain AWD axle shaft seal replacement

Does anyone know the repair procedure for the replacement of the passenger front axle shaft seal on an AWD 2014 Terrain? The exploded parts view show the seal on the inside of the transfer case and the bearing on the outside. Do I need to remove the transfer case to take the case half apart to get to the seal? What other seals and bearing need to be removed and/or replaced to get to the passenger axle shaft seal? Any Special tools needed other than seal puller and snap ring pliers? How many flagged labor hours are allowed? I'm a mechanic that has never had to replace one of these before...

  1. Remove wheel
  2. Remove axle nut
  3. Remove hub
  4. Disconnect sway bar
  5. Disconnect outer tie rod
  6. Disconnect lower control arm from knuckle
  7. Remove axle
Only special tools are a slide hammer, hub puller and a J 44394-A seal protector, the latter is for install.

The dealer quoted 5.7 hours to replace the seal as the parts view shows the seal is on the inside of the transfer case half. The bearing is on the outside. I believe I have to remove the transfer case to get to the seal. Can anyone confirm? If the seal is on the outside it shouldn't take more than 2 hours as you described above.

I have now had 2 dealers confirm the axle shaft seal is on the inside of the transfer case and has to be removed to replace. This is a 6 hr job and the transfer case has to be removed to access it.

Are you doing that repair yourself, and how many miles had the vehicle been driven prior to failure?

My manual just says remove the axle, then the seal. And shows the seal being on the outside. That is for the 6T30/40/45/70/75.

Are you referencing an AWD or FWD? k_rhinehart is asking regarding an AWD and transfer case, not transmission case.

I am a retired GM tech. I just don't have access to GM tech support any longer. I did locate the repair procedure. GM calls the Getrag 760 the "transfer case" which it is not a traditional transfer case as it is a separate extension of the transaxle. The seals are not called axle shaft seals, but rather "transfer case input shaft seal (right)." The passenger seal (part #22) on the exploded parts view is leaking. The vehicle has 63,000 miles. The transfer case MUST be removed, the case half must be separated as these seals ARE on the inside of the transfer case. In addition, the case half seal and left input shaft seal (transaxle to transfer case) needs to be replaced during the disassembly. Repair time is 6 flagged hours. Parts are roughly $120 and the rest is labor to R&I the transfer case. For an $850 repair, it's worth doing yourself, but ONLY if you know what you are doing and have the special tools to disassemble the transfer case.
