Last night i was pulling off from a stoplight and then my car jerked really hard followed by a clinking sound. I parked it last, then this morning i jacked the car up to notice that the driveshaft bolts were loose. after retightening the bolts i went for a little ride. for the first few minutes everything was ok, then my car started making the clinking sound again. i jacked it back up and removed the rear end girdle and here are somethings i found...



After looking a little more I noticed that the was some broken teeth on the gear. My question is is does my rear end have a ford tlok?

 

broken teeth on what gear? the ring gear or the spider gears

and that looks like the stock 7.5 to me

 

On the spider gears. Yea I found out its the stock open diff. I didn't know what the ford tlok looked install. And the fact I was pulling posi traction

 

so you have the stock open diff but your rear tires were both spinning like posi? i dont get it

 

Both tires where spinning like I had a posi traction rear end due to the spider gear on the driver side axel shaft breaking and locking everything up.

 

ohhh gotcha

 

Time for an upgrade.

 

True. I'm getting the money to get an auburn and 3.73s.

 

nice.
