GMC Parts Questions & Answers

  • Q: How to remove and install rear axle shafts on GMC Canyon?
    A: Loosen the rear wheel lug nuts and raise the rear of the vehicle. Support it securely on jackstands and block the front wheels. Remove the wheel and brake drum. Remove the differential cover and allow the lubricant to drain into a container. Remove the lock bolt. On models with a conventional differential, remove the pinion shaft. On models with a locking differential, withdraw the pinion shaft part way, then rotate the differential until the shaft touches the case. Have an assistant push in on the outer flanged end of the axleshaft while you remove the C-lock from the groove in the inner end of the shaft. With the C-lock removed, withdraw the axleshaft, taking care not to damage the oil seal. Some models have a thrust washer in the differential; make sure it doesn't fall out when the axleshaft is removed. To install, carefully insert the axleshaft into the housing and seat it securely in the differential. Install the C-lock in the axleshaft groove and pull out on the flange to lock it. Insert the pinion shaft, align the hole in the shaft with the lock bolt hole and install the lock bolt. Check the cover gasket and replace if necessary. Install the cover and tighten the bolts. Fill the differential with the specified lubricant. Install the brake drum, wheel, and lug nuts. Lower the vehicle and tighten the lug nuts.
  • Q: How to remove and replace the rear crankshaft seal in 3.4L V6 engine on GMC Terrain?
    A: In this step, the transaxle should be removed, also remove the driveplate. Look at the Crankshaft Seal, oil pan, and the surface of the engine block to check for leakage since, in some cases, leakage of the oil pan gasket may give symptoms of a leaking rear Crankshaft Seal. Pay attention to the location of the old seal in order to replicate it in the installation of the new one. Use a screwdriver to pry the Crankshaft Seal off the block being very careful not to mar the crankshaft or the seal bore, the latter which has to be cleaned using a shop towel and cleaning solvent to remove any traces of oil and dirt. A tool called EN-48672 is specifically designed for removing this type of seal without harming the crankshaft or the seal bore; it can be bought at GM dealers and certain automotive toolbox stores. Get a special installation tool EN-48108, which is required for proper insertion of the new seal into place; do not take off the protector sleeve or apply any lubricant to the seal. Crankshaft and seal bore must be clean and free from any nicks or burrs which maybe done with fine crocus paper. Consult the package that the installation tool came in, fit it to the crankshaft in accordance with instructions and then screw it through. Put the new seal in place on the tool, align the drive drum over it and fit the rest of the tool parts onto the shaft, with reference to the fact that the seal is only an assembly in one direction on the tool. Rotate the nut further in order to compress the new seal tighter to the drum and also to make it come in contact with the engine block, after that, you remove the nut and look at the position of the new seal from the drum. Last put in the driveplate and the transaxle.
