  • Remove the four tires from the vehicle, and clean the wheel studs, hub flanges, and the rims centric. Check the vehicles braking system components for wear, remaining brake material, and signs of pending issues. Reinstall the tires onto the vehicle in their best suited locations based on overall wear, torquing all lugs to factory specification. Inflate all tires to the manufacturers suggested pressure, and visually assess the tread for abnormal wear which may indicate a need for a wheel alignment. Reset the vehicles tire pressure monitor sensor locations where required, using the factory approved TPMS (Tire Pressure Monitoring) system, scan tool. Road test the vehicle and confirm there is no abnormal handling characteristics following the rotation. Note: Some vehicles may have a slight drift following a tire rotation. This is due to a pattern that developes in some tires due to excessive time in one location. This condition should improve as the tread conforms to the new location / alignment angle. If drifting would not improve, sometimes an alignment or a cross rotation is required.

The transmission lines are leaking as well and should be replaced in their entirety. All lines for the steering system were removed along with the cooler. The pump flushed, and the lines and cooler assembly replaced with new O rings. Following repairs the system was again flushed and topped off with new power steering fluid. Remove the air box and or upper and lower deflector assemblies to gain access to the transmission cooler lines. Remove all hardware and clamps necessary to remove the cooler lines from the vehicles drive line components. Remove the protector tabs from the radiator, auxiliary cooler, and transmission assembly, and clean the exterior of the connections to prevent foreign material from entering the system. Remove the lock / retainer clips and release the cooler lines from their components. Inspect the sockets and clips for damaged or leaking O rings that would prevent sealing of the replacement lines. Install the new cooler lines and fit into position engaging all retaining clips, and reinstalling the lock tabs. Reinstall the bracketry to secure the lines into their factory locations. Reinstall the air box and or deflectors, and top off the transmission to the proper level with the proper type automatic transmission fluid. Road test the vehicle to verify correct operation of the transmission and check for leaks.
  • Disassemble the rear left door panel and interior components to access the exterior handle. Remove the existing handle and reshape the bent clips caused from the handle failure.
