Hey everyone, swapped a bw1354 into the bronco 2, and on my first test run everything worked good. However this last time I went out and played in the snow whenever i was in reverse and 4 low and had to put the throttle down I heard a massive bang, I have heard this same noise before on my buddies jeep when his t case chain skipped. I was able to also get it to do it in 4 hi (not near as bad) I thought I was able to get it to do it in 2wd but not too sure. So I got it home threw it on jack stands and proceeded to put it in 4 lo, reverse, and loaded it with the brakes but unfortunately couldn’t duplicate the issue.
I had one issue with it though, why only reverse? You would think any tooth wear would be on the forward rotation and therefore skip when moving forward. I have heard these fm145s are known to just grenade randomly.
So I drained all the fluids, popped the covers off both differentials. Didn’t find any missing teeth on either ring or pinion. The transmission had metal in it, but really it wasn’t all that much, pretty normal to me. The t case was very dark (much like when a auto trans has lots of clutch material in it). But not really any metal to speak of.
What I did find was that through the fill hole (I’d say it’s about halfway between the sprockets) I was i able to move the chain up and down a good 3/8”. Lots of slop, now I don’t know transfer cases all to well but it seems extremely excessive. Like if my timing chain had that much play I’d be surprised it was running lol. Anyways anybody with much knowledge on t cases chime in I’d greatly appreciate it.
Also I’m a pretty handy guy, I can rebuild diffs and set gears, rebuild motors etc. if the t case is in need of a rebuild, is it something I should tackle myself or would you guys just recommend pulling it and taking it down to a local transmission shop?
Thanks, chris.
