  Q: How to replace the rear crankshaft seal on Buick Terraza?

  A: To replace the crankshaft rear oil seal, you should remove the engine Flywheel first. During the removal of the crankshaft rear oil seal, do not nick the surface of the crankshaft sealing. Lift the seal out using a flat-bladed tool, insert it though the dust lip at an angle and apply the pressure towards the end of the crank-shaft, repeat as required. During the installation of the new seal, pay attention that it is the reverse style and there is "this side out" on it. Do not apply oil lubrication on the crankshaft rear oil seal and the seal installer (J 34686), as well as avoid putting the sealing lip when removing the protective sleeve so as not to cause damage to it. Clean the crankshaft sealing surface using a clean towel and inspect for burrs or sharp edge smoothing them with crocus cloth. Remove the protective sleeve from the new crankshaft rear oil seal very carefully after that you have to install it into the seal installer (J 34686). Slide it over the mandrel properly so that it bottoms in the collar of the tool. Mount the seal installer (J 34686) to the back of the crankshaft and tighten the screws manually to guarantee square installation of the seal installer. Tighten the wing nut then seal installer (J 34686) till it bottoms up the engine Flywheel; seal installer out, reinstall the engine Flywheel.
