WTF? 1998 2500 Suburban, BB,auto, 4wd. Chevy transfercases are shit. I just put one in my 88 chevy, and my 02 hd needed one for 2 yrs now.

Larry's Shee Posted March 28, 2010 Author Report Share Posted March 28, 2010 No pics, can't hardly see it because of crossmember for front torsion bars. Case is made of magnesium (sp). Cleaned it with stripper wheel then roughed up with coarse emery cloth. cleaned with brake cleaner then acetone, fluid was drained. Applyied two coats of JB Quick weld. Let set for couple hours. covered area about 3x3 inches. Drove about a mile, when I stopped there was fluid on groun didn't even have to look at it. It's almost like the JB didn't stick to the mag. It's the boss's truck, I'm mainteance on a horse farm. Quote Link to comment Share on other sites More sharing options...
Larry's Shee Posted March 30, 2010 Author Report Share Posted March 30, 2010 Well had to join a chevy truck forum. 1998 on there is a problem of the oil pump wearing a hole in the back case half. New rear case half 299, seals, gasket, case saver 77, maybe chain 199. FYI, NP 246 and NP 263HD cases. But be sure I do appreciate everyones interest in this problem. End of story!!
