My transmission in my 06 has a lot of end play, and I’m fairly certain that my input shaft bearing is on its way out. It makes a racket sometimes when the clutch is let out in nuetral which sounds like a grinding/whirring noise. Other times it’s fine. I’ve watched a ton of videos on long range gear, among other hobbyists , but I have two questions that the videos just don’t answer. I’m looking at a total rebuild kit from all state gear, it’s about 1250 cndn but it comes with all bearings, and all of the syncros, plus a shim kit for end play. Anyone recommend this? Transmission has never seen work and it’s got 340k on it, shifting is fine with no grinding as it is. Second, no one talks about end play specs including the service manual. I have been told you want to shim the primary and secondary shafts to a preload of 2 thousands positive. So you find zero with your shims then shim an extra 2 thousands. They say this makes the transmission much quieter and in turn allows for aluminum case expansion after heating up, allowing the end play to stay tight. Advice is appreciated :)
