Re: [MV] GPW clunk and other worries

I am going to give your questions a shot. I am also a recent purchaser of a WW2 jeep and have struggled thru most of what you have asked.

Do you know if you have rzeppa's, bendix or the one I can't remember joints? They get adjusted differently. Make sure you are not on a hard surface when in 4WD. It wil bind up and sound and feel like it is coming apart.

Save your torque reaction spring and you should be able to get springs from Beachwood Canvas or most spring shops.

Manually turn the engine over, find the mark, paint it yellow or white and try again.

It might have a bent shaft, fix your brakes first.

I refuse to give advice on wiring, I am trying to avoid this problem.

There should be a pressure switch on your master cylinder that activates you brake lights. Chances are your master cylinder or the switch are shot.

Master cylinders and wheel cylinders are available and affordable. Old hoses that may look OK on the outside may be restricted on the inside. I prefer to not be cheap on the brakes, especially since this is a single master cylinder and any hydraulic failure takes out the entire system.
