Hi, guys. I have to drop my oil pan to see if the oil pickup tube is clogged. This video shows that it can be done without removing the front differential, but his 2013 Yukon XL underneath looks a bit different from my 2004 Envoy XUV (should be same as XL up front). Confirming that, the Haynes manual says that the front diff carrier simply needs to be unbolted and lowered. However, it then refers me to the section for removing the front diff. Has anyone on the Forum does this (ie, dropped oil pan)? I would especially like to know if all the extra steps in the Haynes manual have to be done, which are not done in the video. These include: 1) disconnecting stabilizer bar links, 2) disconnecting steering knuckle from upper control arm, 3) detaching shock module from lower control arm, 4) pulling CV joints out of the front diff, 5) removing the steering gear! I sure hope it's not that involved!
