How to service and repair the Wiper Pivot linkage on GMC Safari?

First remove both wiper arms and the air inlet grille panel to work safely on the Wiper Motor linkage. Insert the wiper transmission separator part number j 39232 to disconnect the drive link from the Wiper Motor. Remove the transmission to cowl nuts and pull the wiper transmission from the top cowl access points. Put the wiper transmission in place first and attach it with cowl nuts before tightening them to 14 n.m (10 lb ft). Make sure the wiper transmission engages with the crank arm beyond the second detent before sliding it to a height of 1.0 inch where you can put lithium-based lubricant inside the socket before installation. Use the wiper transmission installer (part J 39529) to join the transmission drive link to the Wiper Motor crank arm and reinstall the air inlet grille panel with the wiper arms.

How to service and repair the Wiper Pivot on GMC C2500?

To service and repair the linkage of the Wiper Motor, remove the first step, the wiper arms, and then the air inlet grille panel. Then, remove the four bolts attaching the reinforcement panel and the electrical connector off the Wiper Motor. Take out the two bolts of the wiper transmission assembly and pull the assembly from the vehicle. Use the wiper transmission separator (J 39232) to separate the drive link from the Wiper Motor crank arm. Then, unbolt the two bolts stabilizing the Wiper Motor, and pull the motor out of the wiper transmission assembly. For the installation, you may now use the wiper transmission installer (J 39529) to fix the Wiper Motor to the wiper transmission assembly with the two bolts, which should be tightened to 8 n.m (71 Inst). Following, install the drive link to the Wiper Motor crank arm and proceed installing the wiper transmission assembly on the vehicle, fasten it by tightening the two bolts at a torque of 9 n.m (80 lb in). Reattach the electrical connector to the Wiper Motor, fix the reinforcement panel with the four bolts, and tighten them to 9 n.m (80 lb in). Finally, re-install the air inlet grille panel and the wiper arms and test driving the wipers to be sure they function as expected.

GMC Wiper Pivot maintains blades in position and removes windshields fast and easy so the driver can remain in control. GMC trucks and SUVs leave lines to work, and drag campers with stout boxed frames, powertrain with torque, quiet cabins and driver gadgets such as surround view and hitch guidance that make heavy work seem light on back roads. It is built on a tradition that dates back to 1901, having evolved out of Rapid Motor Vehicle to a range of products that focus on capability over boasting, with every model being supported by brutal durability trials and continuous technological enhancement that hones safety without crowding drivers with acronyms. Powerful suspensions absorb holes, and the smart MultiPro tailgate folds and opens up making it take seconds rather than sweat to load gear. Trust is gained through reliability and the momentum is maintained through word of mouth. Then stroke the limelight is the Wiper Pivot units, which, when storms strike, plunge concerning the blades with low friction and, in spite of highway wind, resist slap. Each is equipped with a single Wiper Pivot on the driver side and another on the passenger side and the driver arm is slightly more expensive since it has wider sweep and greater load. The alloy of hardened steel and engineered plastic rubs off years of grime and ice. The component clips simply onto linkage rod in any of the body styles without any hassle and all GMCs have the clear view they want. Ongoing motions check ensure that a Wiper Pivot is aligned following innumerable cycles and thus the visibility is at its optimum when the weather is not pleasant.

Q: How to service and repair the Wiper Pivot on GMC C2500?
A:
To service and repair the linkage of the Wiper Motor, remove the first step, the wiper arms, and then the air inlet grille panel. Then, remove the four bolts attaching the reinforcement panel and the electrical connector off the Wiper Motor. Take out the two bolts of the wiper transmission assembly and pull the assembly from the vehicle. Use the wiper transmission separator (J 39232) to separate the drive link from the Wiper Motor crank arm. Then, unbolt the two bolts stabilizing the Wiper Motor, and pull the motor out of the wiper transmission assembly. For the installation, you may now use the wiper transmission installer (J 39529) to fix the Wiper Motor to the wiper transmission assembly with the two bolts, which should be tightened to 8 n.m (71 Inst). Following, install the drive link to the Wiper Motor crank arm and proceed installing the wiper transmission assembly on the vehicle, fasten it by tightening the two bolts at a torque of 9 n.m (80 lb in). Reattach the electrical connector to the Wiper Motor, fix the reinforcement panel with the four bolts, and tighten them to 9 n.m (80 lb in). Finally, re-install the air inlet grille panel and the wiper arms and test driving the wipers to be sure they function as expected.
