When your Chevy hits a Knob, the suspension deflects slightly to absorb the blow of the Knob. As a backwash of the movement of the suspension, the angle of the Supple suspension manner, Towards the non-flexible engine and transmission operation, changes.

Instructions
1. Block the wheels with wheels chocks on the contradictory stop of the vehicle so it can't roll during the repair. Roll a floor jack under the centre of the differential and lift the wheels off the ground.
2. Unbolt the handle shaft from the differential by removing the 7/16-inch nuts from the U-bolts on the U-joint. Use the U-joint press to push the new cap into the drive shaft yoke until a retaining clip can be snapped into place on the cap. Repeat the process on the remaining caps.6. Slip the round clips into the drive shaft yoke and push it into the retaining grooves in the yoke using a screwdriver.
Turn the centre shaft on the press with a 13/16-inch wrench until it contacts the U-joint. Generate confident the factor is lined up on the Seam and draw out turning the centre shaft until the U-joint cap is pushed elsewhere finished the contradiction extent of the stuff. Loosen the centre shaft of the baggage and appliance it to push the remaining caps gone of the propel shaft in the equivalent system.
4. Turn on the torch and heat the operate shaft yoke. Most inventory Chevy U-joints are retained in the impel shaft yoke by an injection-molded plastic retainer. Heat the yoke until the plastic melts and expands absent of the gap it was injected into in the yoke. If the joint was previously replaced, it is retained by small spring clips in the sides of the yoke. Compress the clips with a pair of needle-nose pliers and pull them from the yoke.
5. Wipe off any rust and old grease with a shop rag. Carefully slide the caps off the new U-joint. Screw the new grease fitting into the cross-piece using a 5/16-inch wrench. Slip the cross-piece of the new joint into the drive shaft yoke and push one of the caps into the drive shaft yoke. Slide the drive shaft outside of the transmission whether it is a one-piece impel shaft. Whether it is a operate shaft with two sections, unbolt the carrier bearing from the frame cross-member, using a 9/16-inch or 15 mm socket and ratchet, and slide the guide shaft from the transmission.3. Slip the U-joint press onto the coerce shaft according to the manufacturer's directions.
Reinstall the drive shaft and tighten the retaining nuts and bolts securely. Grease the new U-joint using a grease gun. Lower the vehicle from the stands to the ground and test-drive.
