Guest M37Dodge Posted June 27, 2008 Report Posted June 27, 2008 I need a replacement ham/pumpkin. Apparently mine sat with water in it and the bearings got pitted. So, if you have a spare differential, let me know condition, location, ratio 4.89 preferred (most common) and price. BTW: the 1-ton differential should have a casting # ending in 241 facing the driver's side frame rail on the rear ham- it is removed by popping out the floating axles, disconnect the driveshaft, and take off the 12-14 (I forget #) nuts on the ham/pumpkin so it can pop out the front of the rear axle housing. It is like a Ford 9" or Mopar 8.75 ham style rear. Thanks from PA. -Drew M. Quote
oldmopar Posted June 27, 2008 Report Posted June 27, 2008 If you have to replace the rear you may want to look for something more highway friendly then the 4.89 .My 46 wd has a 4.3 not sure what the other ratios were for a pilot house but you can do better the 4.89 unless like your name says you have a m37 then I am not sure what you can use Quote
Guest M37Dodge Posted June 28, 2008 Report Posted June 28, 2008 5.83 was standard with 4.89 as an option. I run surplus 11.00 x 16 tires (42" high) so 4.89 is fine for me. Aftermarket (Richmond) make the rear in 4.89 also. This rear was used from 1943-1958 in full floating 3/4-1 ton Dodge trucks (both 2wd and 4wd). Quote
Dodgeb4ya Posted June 28, 2008 Report Posted June 28, 2008 Every 1948-53 Dodge b1-2-3-4 1 ton I've owned /parted out is or was a 4.3. Power wagons are a lower ratio. 4.3 is a ok kinda road ratio. 3.9 which I have never been able to find would be great for a 1 ton. They are a real hard to find rear end. Bob Quote
Don Coatney Posted June 28, 2008 Report Posted June 28, 2008 M37; Where are you located? Your profile does not say much. Quote
Guest M37Dodge Posted June 28, 2008 Report Posted June 28, 2008 True, my profile says little. I'll add to it. I am assuming you wanted to knwo where in PA? Lancaster area - known for Amish, car shows (largest rod tod show in world (York PA) and largest antique car shows pre-1949 (Carlisle and Hershey in Fall) and chocolate factories. Quote

So you live near Intercourse, Bird in Hand, and most importantly Dave "Grey Beard" Erb. Search the profiles for Grey Beard and contact him in New Holland, Pa. He can and will help you. Quote
Guest M37Dodge Posted June 29, 2008 Report Posted June 29, 2008 New Holland is not too far from me. I'm on the western side of the county. Quote

Guest M37Dodge Posted July 2, 2008 Report Posted July 2, 2008 The 241 casting diff is not rare. All M37's, flat fender power wagons, and WWII WC 3/4 and 1.5 tons after 1943 had them. However, the army trucks are geared 5.83 and nearly all PW had the same. I am trying to improve on mileage by finding a diff out of a civilian 2wd 1-ton, which had 4.89 as an option. My M37 has 11.00 x 16 XL tires to cut down rpms already. My 230 is out of a 1951 Coronet and has higher compression and hp than the T245 factory 230. Quote
