Synchromesh starting to fail

[Tom88]

Hi all,

I recently bought a 93 4runner (LN130R) with some friends to drive from Australia to Scotland. So far it's doing a bang up job. i have noticed though the synchromesh on third is starting to get a bit dodgy, and it's even slipped out of third a couple of times. At the moment it's not a huge problem, but we're only in cambodia and still have quite a way to go.

My question is basicaly is this a common problem? Is it likely to deteriorate quickly, and if so is there a way to fix it before it gets worse and we end up with no third gear.

Any help/insight would be greatly appreciated, cheers.

You are asking in the wrong forum. You have a 2nd gen 4runner, this is the 3rd gen 4runner section. Delete this post and head over to the 2nd gen section; they will know much better than us.

This is a common problem for all manual gear boxes. Its usually from grinding the gears over and over and not changing the fluid. Yes it will start to deterate. You can pull it apart and replace the synchros but if you dont overhaul the entire trans it could just be a waste of time. When I have done that in the past something else ends up failing.
