I have the 'original' Quadratrac that came with the truck when I bought it 4 months ago, supposed to be 1977, it has the Mile Marker 2x4 OD kit in it. The story goes the chain was slipping and they found a deal on an existing one so they swapped it out. I was going to do nothing but the existing one is leaking now out the front seal. At least I have a spare.
Bought the BJ's rebuild kit with chain. This is the first time I've been inside one of these and I replaced all the seals and got the chain on, it's all back together but I have some questions.
-One of the planetary gears is tight, not terrible but not free. The opposite gear is so free there's about a .030 gap and I can click it up and down. The other two seem normal. Should I be concerned about this?
-So looking at it on the bench from the back without the low range attached and turning the driveshaft yoke clockwise, the gear the planetary set attaches to, climbs out of the case towards me. If I turn the yoke in the opposite direction it sucks the gear in .067" and I can see that the back of planetary gear assembly has been rubbing on the transfer case enough to score it up. Putting the snap ring on reduces the play but when turning clockwise it still draws it in hard enough to drag on the case noticeably. Which way does the driveshaft turn in drive? Is this a problem only in reverse?
-When locked into 4wd there's about 35 degrees worth of play in the driveline between the front and rear driveshafts. So if I hold the rear driveshaft yolk I can clunk the front one back and forth about 35 dregrees. This seems like too much.
I don't have any parts left over
but unfortunately I didn't check any of this stuff before I took it apart.
I'm just trying to be sure I have it together properly before I go through all the effort to put it in.
