Hi all, In midst of frame replacement/frame-off resto on 97 TJ. Finally turned corner from disassembly and prep/coating new frame to reassembly. Replaced D30 inner seals, inspected innards - looks good. Figured while I have it on the bench I'd add outer seals - keep crud outta the tube. I bought: Ten Factory MG21102 Red Dana Axle Tube Seal, Pair (30/44) Added a bit of lube to the outer rubber of the seal, and a bit to inner surface of the "long side" tube, and pounded it in with a hammer. easy/done. For the short tube, I've beat on it much harder - still ~1/2" away from seating. FUD sets in. If I pound it all the way in, and there's an issue, it'll be a Bitch to get out (sawsall?), but if it works - done. continue w/rear axle, brakes, new suspension, and on we go. Does axle tube ID vary from side to side? Or perhaps rust build-up is the culprit? Or just suck it up buttercup, and beat that sucker in there?
