Transfer case / rear axle play

BigGreenBronco · Mar 6, 2013

Hey everyone I need some help to determine if my ring and pinion is too loose or if my transfr case is messed up. When I put the truck in neutral i can turn the driveshaft about 3/4 of a turn. The gears in the rear axle wwere swapped to 4.56 by a local mechanic.

It's not your transfer. Best I get is 1/8" to 1/4" play.

3/4 turn would be an issue in the 3rd. member.

Hey Big Green,

3/4 is WAY too much slop! Check your U Joints too. With that much play the rear end has problems.

I pulled the cover off my differential it looks good I didnt find any unusual wear or chips. The u joint closest to the rear axle seems like it has some side to side play. Also the driveshaft seems to only turn about a 1/4 of a turn when the truck is in nuetral. Is it possible the u joint is just bad?

One clue would be "noise"

"The u joint closest to the rear axle seems like it has some side to side play"

Hitt'n the grease zerks would cure that but something to keep an eye on.

If the shop didn't put on a new nut that locks the yoke/pinion together., it can work loose creating slop. This is usually along with noise & vibration.

There's usually a specific torque for that nut.
