does the ring and pinion drag(real tight , with a slight grab feeling) when first installed,

I know there is a break in,
i replace the ring and pininon w/ new bearing all around.
crushed the pinion in , and seated the diff, but when i tighten the drivers side bearing cap it lock up completely, the pass side has no effect on how tight it is.
i resused the shims i took out all around.

any thoughts,?

Thanks,
louied
 
You could PM READYMIX. He really helped me out with r&p installs. What axle? Sounds like a 14B with end caps?
 
lol you need to re-set your gears, you are going to need a dial indicator and check it all.
 
YOu should have checked the backlash before you took it apart. What axle is it? Is it cocked? Sounds like you dont have enough backlash.
 
its a 10 bolt 373 gears, i checked backlash prior all looked goo about 7on the dial, i put it together and sound ok i gotot put her on the the ground , and see how it sounds,
 
I'm getting the impression that you did not check and adjust pinion depth. Did you run gear patterns with gear compound. If so post the pics and we'll see what it looks like. Like said above, it does not sound like you set your backlash correctly either. You did metion that you reused the same shims. More often than not you cannot reuse the same shims and get the same results from new gears. Each gear manufacturer is different. From my experience different manufactures with the same ratio equalled to completely different pinion shims to get the correct pinion depth. BTW the crush sleeve only sets the pinion bearing preload and has nothing to do with pinion depth.
If you run it as is to "see what happens" you can count on major problems.
 
You sound like u know what ur doing, this has to be one of the most difficult projects i have tried, repalce just about everthing on the RIG except the R&P.

I reused the shims, pininon and carrier. i do not have photos of the track pattern, i feel like it going to be F#$^@#%$%^ UP, and hate to waste new gears like that, but its like when we go off road and break something, then back to the shop to rebuilt it ! Right?

I m looking for a reputable shop to finnish what i have started in the rear.
What would be a fair $$ to set up the rear , 10bolt.? mind u the bearing are new , and the R&P are new( as of now),

thanks for the info ,
 
Sounds too me like you got in over your head....so to say.

First set you pinoin depth then the BL, then chack the pattern. You should have new shims when you install gears. I can go really in depth on how to do it but it sounds like you have accepted defeat already.
If not i can help. Do you have the proper tools for the job.
 
gears are one of those things ont he truck that are vary precise when it comes to getting it correct. you cant just slap them in there and expect them to work.
I think you should go find a shop to fix it before they get messed up. :crazy:
 
WHat gearset did you use (brand). SOmetimes you can get lucky and wont need to change shims when its an OEM or good quality gearset, such is the case with Danas.
 
PTP by RIchmond; Gm85373

I took er out around the parking lot and it actually feels good, no grinding or harsh noise, just a lack of power. also installed the TCI 4x4 trans w 2000 stal converter gota fine tune the TV cable i think.....
 
Reusing the same pinion shims only work if you are installing factory gears of the same ratio. If you are changing the ratio then you really need to understand the proper set up of the gears. I have done a ton of 10 bolts, ifs fronts d44's d30's d35's 14 bolts, and a butt load of toy 8" for all my Yota wheeling buds. Oh btw, I collect a paycheck doing stuff like this. Do yourself a favor and run some paint and see what you got. Catch it now before you run you rear to hot and really cost some coin. I charge 3.5hrs labor to set up a 10bolt rear. Multiply that by the shop labor rate and thats how much it will cost. Good luck.
P.S. It's always cheaper to do it right the first time.
 
ring gear 373

take a look at these pics, cut and past the link above to see the pattern of the ring and pinion, and let me know where i stand..



thanks

I got your e-mail. The pic you posted on the far right makes it seem like the pinion is a little too shallow. That is the coast side though. What does the drive side look like?
 
Small pictures, but it looks as though you are way to shallow on the pinion depth. Did you remove the old pinion bearing on the old pinion and swap out the pinion shim? Try using yellow compound or white grease so it is easier to see the patterns. What is you backlash at now?
Start by going a thou deeper and recheck. Go from one extreme to the other and then fine tune from there.
 
i reused the pininon shim, and carrier shims.

new bearings in diff and pinion

where do i get yellow compound?
