I'm putting my M-37 front axle in my truck a '41 1/2 ton wc-4, getting ready to put lockers in.
The old 1/2 axle has a narrower track (one inch total spring pad to spring pad)
The trucks front shackles are offset inwards one inch. I reversed the shackle plates inside to outide, so that they offset outwards.
This alligned the springs right over the m-37 axle spring pads. The pinion yokes are interchangeable, so I did that.
Because the old spring pads were a narrower track. The passenger side one was actually mounted half way up the side of the differential housing on the old axle.
The drivers side one is 1-1/2" tall to match them up. The M-37 front axle pads are lower. When I put the axle in, the pinion yoke was resting againt the oil pan.
So I need to install 1-1/2" lifting blocks to make up for the difference. I remember charlie talking about adding castor wedges, I think he said 4.5 degrees.
I want to make the castor wedges, and the lifting blocks all one piece and weld them to the M-37 axle spring pads.
Question: Does the wedge go in narrow end to the front, or to the rear?
Hopefully to the rear, that will pull the pinion yoke down away from the oil pan a little further yet.
Also, if my math is correct, If I were to make a 6" wedge, it should be 0.47" thick at the thick end. Does this sound about right?
If so. I think I'll make blocks 1.5 inches thick at the narrow end. 2" thick at the wide end, and 6" Long. This will give me the 1.5 inches lift I need (actually 1.75") and correct the castor angle at the same time.
Ideas? Comments?
Thanks.
Sean.
