[Chrysler300] 300H rough idle/ now about car "locking up".

["Michael Moore mmoore8425@xxxxxxx [Chrysler300]" <Chrysler300-noreply@xxxxxxxxxxxxxxx>]

Some time ago,  I moved my car in my garage and it locked up as though it had hit something when I moved either forward or backwards a couple of feet. 

Because I HAD to move it, I gave it gradually increasing amounts of throttle and it did move as though I were driving through locked brakes. 

Here’s where things are now:

1. Removed both rear drums, and found both rear brakes were normal (they were rebuilt a couple of years ago.) 

2. Removed drive shaft  and found a rear u-joint was worn but showed no signs of anything locking up.I could turn the diff input shaft either direction  without a problem.  

3, The diff was shipped to Randy’s for disassembly, inspection and rebuild . It was in good shape except the Power Grip clutch pack was worn (350,000 miles). 

4. I spent a long time on the phone with Jeff Carter (who sold me replacement axles as mine were stripped or worn on the taper),and he suggested I check out the e-brake more throughly. I just now pulled that drum, and it looks just like it did when I put it together several years ago with new lining. It is also not my smoking gun. 

5. Jeff Carter suggested I check for a broken trunnion pin on the front U-jpint,  which I will do. 
If it still does this (no reason found not to!) , I plan on cycling buttons on transmission between 1 and D as that is a different fluid path and may show something.
If anyone has any further suggestions , I would sure be grateful!


Thanks, 
MIke Moore
