Tire size, bearings & brakes Questions.

[Les Kovacs]

Thanks Rob....I think there is about 5000 miles since a full rebuild on the jeep which included new kingpin bearings & races....I just wanted to see if I can maintain the bearings longer if I pumped in fresh synthetic grease via the cap bolts. Last spring when the front tires were off I did swing the knuckle back and forth...it was very smooth. I remove the front axle rear hub/knuckle bolts and squeeze in synthetic grease every 2-3 weeks then lock in the hubs for a while so the grease can be flung all over....I think this helps as well.....not sure though.

Any idea the size of the 67' M38A1 brake shoes?....front axle is labelled as Dana 25.

Regards,

They should be 9" x 1-3/4. There is the possibility that you can have the older brakes from the 52/53 series of Jeeps, which had anchor pins on the bottom, but most likely you will have the same shoes Jeep used for over a decade. NAPA has them under part number TS40.

The shoes Rob refers to should look like this...

The sets also go by NSN 2530-00-307-8860. Same shoes front and rear.

Thanks Rob and Wayne for the pics....Rob....thanks for the Napa part number....off to do some ordering & shopping.

Regards to both...

Rob....one more question...I was going to order all the brake parts from a US site until you turn me to the TS40 Napa part for brake shoes.....I just called my local Napa and they have a set for $45.00 CAD....as opposed to $40.00 US on US military parts sites....what a savings!....OK....I am also looking for front & rear wheel cylinders....any idea it Napa carries them and if so....what are their part numbers if you have it on record.

Hit up Jason Ginn about kingpins. My CDN3 had a horribly loose front right. He had the touch to take it apart, inspect and reinstall. You and I probably read the same articles. IMHO, pay someone who knows if you don't know.

Ditto on Rob's advice about brakes. The CDN1 and 2 were never especially good at stopping. The CDN3 has bigger brakes. If you find a junker CDN3, seriously consider swapping out both axles. The ratios are the same.

Napa will have the wheel cylinders and at good prices. I,m in mexico right now working off a tablet, so digging in to napa,s jobber site isn,t going to happen, but if you have your napa dealer look up the cylinders (1 inch and 3\4 inch) for a 1950s Willy's they will be what you want. Even CDN tire carried the smaller ones for about $10 back in the day.

The best thing about the cdn3 axles besides the brakes are the one piece rear axle shafts. Much stronger and more reliable. However the rear axle is also a different diameter so will require the cdn3 u bolts and bottom plates.
