Re: [Chrysler300] Sudden drive train lock-up

Thanks David,
This has been a bit of a comedy!
I decided a couple of weeks ago to try to get to the bottom of why my car ran lousy-as my camshaft is non-stock (Barnes) I want to try everything else before I replace it with a stock 300H camshaft I got from Fern.
I earlier discovered my mech advance was coming in way too early ca. 300-400 rpm making a proper idle impossible, so it was rebuilt by Philbin and is performing as it should.
New solid wire  core ignition wires. New coil.
Found vacuum leaks last week, from the intake manifold, but then the 35 year old starter failed. I spent a few days (off and on) crawling around under the car and over the car replacing it. (Great exercise!)  I decided to cut the exhaust pipe back near the muffler to get the downpipe out of the way so I will  have that to contend with eventually. But the car began this sudden stop business when I tried to move it. So that must be my next order of business. THEN I will get to install my new intake manifold gasket!  
 Best Regards,
Mike Moore

No David, I have not. I am going to talk to a local machine shop which specializes in drive train work. I may remove the entire rear end and haul it down there, as the u joints don’t  seem that bad. 
(Do you know how much an entire rear axle, drums etc weighs? I am guessing at least 200#.)
Thanks, Mike Moore

Have you had either one of the axles out recently?

Not really sure how your rear is assembled, but it sounds like the center pin has come loose in you spider gears and is hitting after one revolution of the tires/pinion. Go forward and it comes around and hits again.

 When I backed it up, after approx 3 ft the drive locked up sharply, as though I had hit something. But I hadn’t,  and all 4 wheels were clear. It did the same thing going forward-locking up after just a few feet.I did this several times and the distances prior to lockup seemed the same.

I was able to give it a lot of gas and slowly it would move, but something was straining.


This afternoon, after completing new starter motor installation, I dropped the driveshaft to have a suspect rear U-joint replaced tomorrow, but I see nothing which looked like it was hitting.

On jack stands under the axle, I also am able to rotate both rear wheels in either direction continuously without a lock up. My next step is to remove both rear drums and ensure there are no  broken  brake springs, but if I don’t see anything there, I have no idea where to look next. There are no unusual noises when I rotate the wheels.

Any suggestions?


Thanks, MIke Moore
