3rd Gear Syncro Replacement

[Chris@Rvengeperformance]

Well my 3rd is blocking me out. It isn't grinding yet, but I want to replace the syncro before it does damage to any hard parts. 1st,4th,5th are perfect and 2nd is "ok".

I have a new 2,3 and 4 oem syncros coming from jacks transmissions and I'm going to replace 1st with my low mile first out of my other gear box.

I've replace the 1st and 2nd syncros before and it is really no big deal, but the 3rd/4th look a lot harder. It looks like the shaft needs to come out of the box completely by pressing it out of the end case, 5th needs to be taken out of the way, and then you can get to the meat of 3/4th.

Anyone have any more info? Pics would be ever better. Obviously I have the getrag manual.

I need to get this done quick as I want to replace them before the NG if I can. When I had the trans apart to put my 300m output shaft in the gear engagement teeth looked great, so I'm not expecting any serious parts that need to be replaced. The box is quiet, and does not have excessive backlash, so I am going to leave the bearings alone.

The other thing I'm considering is just running syncromesh for while I have redline mtl in it right now.
