Today I park in a pretty steep driveway at a jobsite and put it in gear let off and it rolls forward like normal. Then I get out and I here it creaking. it would creak...creak...creak...then lunge forward and you can see it slowly moving down the driveway. Today was the first day it was then bad but it has been like that since it got to 99k. Its at 115k now. Runs alittle rough off and on. I'm changing the spark plugs and COP's next weekend. I'm thinking it compression but does anyone have any ideas?

 

If the clutch slips it could roll too

 

I thought about that too. I did replace the clutch at 98,900 miles after the slave cylinder exploded. I do have a **** load of fluid come out of the bellhousing but its not clutch fluid. I'll have to check the tranny fluid tomorrow.

 

I also have a leaking rear pinion bearing seal but the diff is still full.

 

I would never just use the gear/compression to hold my truck on a hill. Seen to many crazy things happen.

 

I don't really have a choice. My e-brake has never worked. I haven't had time to replace the cable. it'd probably be a good idea though.

 

Carry some good wheel chocks till you get the ebrake working.

Fluid in the bellhousing could be the rear main seal.
