92 TOY 4X4 NOISY 5th Gear

Sep 02, 2004 2 Replies

This is a constant noise when it's running in 5th... still shifts fine. I debating the merits of a replacement used, or replacing the



5th gear assembly my self. I have rebuilt many engines, but have never been into a manual tranny, any opinions on how hard it would be to replace the bearings and gears involved in the 5th gear assembly???? Any special tools???

Thanks Mark...


Early 5spd's were notorious for rear lay shaft (counter-cluster shaft) bearing to pit and being very noisy when in 1st, 2nd & 5th gear. These gears are @ the rear of the shaft and load that bearing. good luck! kend

one of the roller bearings has a race and balls chipped, and if you don't get it fixed ASAP, the hardened chips will float thru the gearbox and 'print' pits into everything that meshes together. I elected to let the dealer overhaul my '85 4runner trans, after I pulled and re-installed it myself, cost me $800. cdn. They replaced all the bearings because of the pitting on them, I had to drive it about 1000 km before getting home after it started to growl in 5th, drove all the way in

4th. I took a few bearings apart to see how badly pitted and they would not have lasted very long. The cause of the failure ? the dealer service manager said it was caused by 'lugging' in 5th, not shifting up or down soon enough, common problem if you lug these in 5th.. Jim
