I have an 88 Suburban, 90k miles, that seems to be leaking ATF throughthe rear driveshaft slip yoke. I've cleaned it up twice, and bothtimes the ATF appears on the slip yoke before anything else. It prettyquickly spreads as it slings all over the place and drips back down onthe transfer case.How do I seal the yoke? There appears to be a pressed-in plug in themiddle of the yoke. I've got a picture here- do I fix this?a) Slather it with JB weld?b) Knock out the plug from inside the yoke and reseal it with RTV?c) Weld it?While I'm at it, what holds these u-joints in? It looks like a smallplastic pin is all that keeps them in the yoke. (See picture). If Idrop the drive shaft I'm tempted to do the u-joints and rear seal onthe transfer case while I'm at it.Suggestions?-RCR.Clarkespam RTP, NC, USA
