WELL TODAY I WAS INSTALLING A NEW DIFF. CAUSE I BLOOW IT OUT SUNDAY NIGHT , SO I WENT AHEAD AND BOUGHT A 3.73 INSTEAD OF USING MY STOCK 3.42. RIGHT WHEN I WAS DONE THE REAR END WOULDNT MOVE, IT WAS PRETTY HARD , SO I WAS WOUNDERING IF YA MIGHT HELP ME? THANX


GREENMILE UNDERCONSTRUCTION

 

so will it not move or is it just really stiff? pretty hard meaning like when you drive with the parking brake sort of feeling?

 

If your new ring gear was a 3.73. Did you install the appropriate pinion gear? If not, there is your problem. 3.42 pinion with a 3.73 ring wont play very nicely.

If you did, check the gear backlash, its probably too tight.

 

I Bought Both Gear Ring And Pinion. And Yeah Its Stiff.

 

How much preload is on the pinion?

 

Pre Load?

 

Once you tightend the pinion nut did you put a inch pound torque wrench on it to measure the load of how hard it was to turn or the drag amount lets say.

 

Did you replace the crush sleave? If so did you get the new one to crush properly?Did you install all new bearings and races?

 

everything new, except the sleeve.

 

i agree with checking the backlash
