  Q: How to replace the front cross-member in a 4WD on GMC Envoy?

  A: To replace the transmission cross member on a 4wd vehicle, one must jack it up and apply support to the transmission with a suitable stand or jack before starting such procedures. Take off the nuts that hold the transmission mount to the transmission support, then raise the transmission. Next, remove the vertical bolts that hold the transmission support from the frame, and the horizontal nuts and bolts securing the transmission support. After removing, take the transmission support from frame. For installation, set the transmission support back on the contour of the frame and loosely mount horizontal nuts and bolts. It is essential to follow the fastener notice in service precautions. Next, roughly mount the vertical bolts holding the transmission support. Tighten horizontal nuts to 50 n.m (37 lb ft) and horizontal bolts 100 n.m (74 lb ft). Reduce the transmission, attach the nuts to transmission mount, eliminate the stand or jack, and lastly lower the automobile.
