Spider gear has play

Hey guys, first time in the rear unequal and i got some issues. One of my spider gears has play up and downward, its making a clicking noise when u spin information technology.

I've searced the forums and googles some diagrams. All i tin can tell is there is a washer behind the spider gear that is concave. Is it possible it has flatened allowing the movement, or practise i have other issues?

This is with the rear carrier removed from the axle housing, the pivot is slide in the gears, with the lock commodities removed (it broke). I shouldnt accept any play, correct?

I originally thought it was my pinion bearings making the noise, then idea it was the carrier bearing. Replaced the carrier bearing and institute this noise instead. Im tired of replacing parts that are good, lol.

First, which differential do you have? If merely one pinion gear has play and then something is incorrect. Both of the pinion gears should take the same amount of play. If i of them has more than the other so the one that is the tightest is conveying all of the load and half of the force is gone.

It'due south manufactory 10 bolt, eight.v" non posi. Not sure of the ratio. I was hoping u'd chinkle in big gear caput.

I rechecked and i do accept play in both pinion/spider gears. Its about the aforementioned for both sides. Is this normal?

The gears motility up and down slightly. When u spin them they brand a clicking sound when they motility. Would the lock bolt being removed/broken have anyting to do with this?

It'south probably simply due to wear. If it's not excessive I wouldn't worry about information technology. If information technology bothers you so y'all could upgrade to a Posi.

10-4. I'll just put it back "as is" for at present, if she goes then ill upgrade. Thanks for the help gearhead.

On a side note, i already swapped the right carrier begetting, thinking it was the noise. The carrier is too tight to fit back in, or i aint holding my rima oris right when im doin it. Im figuring the shims demand adjusted, divergence in bearing size i gauge.

When i removed the old begetting, i saw no shims behind information technology. Theres a shim betwixt the axle tube and the carrier, is this the adjustable one? Or exercise u adjust shims backside the begetting on the carrier?

you lot should use the same shims now, equally there were b4. New bearings shouldn't impact the shims/side clearance. those shims, iirc, arrange the backlash on the gears. you change them, and you will toast the gear set. it is non uncommon to accept to slightly "persuade" the unit of measurement in with a rubber hammer. Likewise brand sure the carrier bearing you swapped is fully seated.

Hopefully you kept the spacers on the same side that they came out of. If you didn't then you could accept some problems. The quondam bearings were probably worn enough that they allowed the differential to be a footling loose. Put the left spacer in first with the differential and bearing races. Then use a screwdriver to push everything to the left side and get the right shim started between the race and housing. Apply a minor hammer to tap the spacer into place. It's going to be tight, but it should get. Don't force it toomuch or you will interruption the spacer.

Exist sure that you have the bearing completely seated on the differential. I've seen several people who just pressed the bearing on and didn't get information technology seated completely.

I didnt realize they fit and then tight, it merely slide correct out. The begetting is fully seated, the carrier sticks out past it just a bit. I've kept all the parts on the correct sides to.

I did clean off on of the spacers to see if in that location were any numbers on it, at that place werent. Anyways, i cleaned quite abit of crap off it. I effigy if i clean both ill gain a trivial bit of clearance.

Should i lube the shims besides, or keep em clean? Just seem like sum unequal fluid would help the terminal shim tap in.

• #9

Oil isn't going to hurt them. When everything is set right you lot should not be able to pull the differential out by mitt. The bearing preload should be tight enough that you have to pry the differential out of the housing. If it is likewise tight yous will damage the shims or housing when you drive the correct shim in. If it feels similar the shim is shaving metal off of the housing, or the shim breaks then it's too tight.

Ok, got the carrier back in. She went in super tight, but shes in.

I measured the preload on the pinion afterward the carrier was back in and i got 17 in lbs tq. It was 5 in lbs tq with but the pinion. Subsequently i put the axles back in i got 21 in lbs tq.

Those numbers seem right for a mill 78 non posi rear, with ane new carrier bearing?
