FITS: 1998-2007 GM transfer case models 136, 146, 246, 261, 261HD, 263HD, 263XHD, 261XHD - IMPORTANT: Install by a Professional is highly recommended - REQUIRED FOR INSTALL: Transfer case needs to be removed and disassembled ---- Here is the best upgrade you can make to your GM transfer case(model 136, 146, 246, 261, 261HD, 263HD, 263XHD, 261XHD). Prevent the ever increasing problem of pump rub. What is "pump rub" The GM transfer cases use a gear pump inside the case that is driven off the mainshaft. The pump forces oil to the planetary as well as the drive sprocket sleeve. Because the pump is driven by the shaft, the housing of the pump must 'float' in the rear housing. There are 5 tabs around the housing that fit into spots in the rear housing to position the pump. Over time, the pump can start to wear on the rear housing. GM installed a spring steel clip in the housing intended to prevent wear but the clip can break and render useless Being that the pump housing is aluminum and is a harder material then the magnesium rear housing, it can wear a hole in the rear housing and cause a very small leak. This leak is high enough in the case that it typically will not leak when vehicle is not moving and therefor not leaving any drops on the ground. Typically the condition is not found until there is transfer case damage from running the case out of fluid. Avoid costly repairs to your transfer case by preventing this condition.
- The updated factory anti-rattle clips do not prevent pump rub - this is the only kit available that will PREVENT pump rub. This kit does NOT FIX cracked housings, it only prevents pump rub from happening.
- IMPORTANT: Install by a Professional is highly recommended - REQUIRED FOR INSTALL: Transfer case needs to be removed and disassembled
