Initially, there were shifting issues with the Bmaxes. One would hang in forward, and the other would "bang" going into forward.
Then the lowers about fell off after a fairly hard run Broken studs on both sides, and of course lube loss. Lowers were actually just barely hanging on by 2 remaining fasteners. Could wiggle them side to side by hand. Could pull open a visible gap with your hands between the uppers and lowers.
Then after fitting them with HP studs, we ran a poker run with them "fresh" back from the BShop with a thumbs-up to go for it. On the last leg we let it eat for the 6 miles back to the dock. Smelled gear oil. Went to idle and one wouldn't come out of gear very easily. I crawled back and looked - one side was blowing gray lube everywhere in the engine compartment.
Put her on the trailer and both propshaft bearing sets were toast. One loose, the other one was a complete goner. Back to BShop. I expect that to be a setup issue in the drives, but it's definitely getting old...
Got 2 hours on them testing motor stuff so far.
No issues yet. Fingers crossed (except for the middle one which is fully extended).
