In 1988 short box automatic 2 wd comanches is the rear end a posi-trac or a trac lock?

 

 

it varies by vehicle and original purchaser's order sheet.

 

only way to know is to run the VIN number, or look inside the axle.

 

 

but if it had one it would be a trac-lock.

Posi-trak is a registered trademark by Eaton for their clutch based limited slip differential used in GM cars only.

i thought the rear end was going in mine turns out its not..the bearing on the passenger side axle was long gone. so i bought a new kit for it and put it on but there seems to be alot of play "in and out" none side to die or up and down how much should there be? or do i need to move the new spacer farther in on the axle?

If you have an '88 with the original axle, it's not a c-clip and the axle is located laterally by the position of the bearing on the shaft, and the retainer. If you have excessive "in and out" free play, the bearing wasn't installed correctly on the shaft.
