I am trying to ID which front axle assembly I have in my 97 Dodge Dakota
4x4. It is a 10-bolt cover and looks octagon in shape. I know it is a 3.55 ratio and the Tag on it has the following: 39-11 3 55 On the right axle tube is the following: 2 47064 That is the only ID info I could find on it. Looking around the net I have seen 2 that could be the unit. One is a Dana 35 IFS w/cv axle shafts RG Dia 7.56" And the other is 8 1/4" Chrysler w/cv axle shafts Maybe the 2 are interchangeable in the Dakota, I would think the Dana would be a better replacemment, but I noticed the smaller ring gear which may be a weaker unit. The one in the truck that I pulled out is broken in 3 places from the previous owner. I pulled the engine to rebuild it and that is when I noticed the front axle was shot. I am going to rebuild the motor with stock components, but due to oil pressure problems with the pressure I was going to replace the pump with a high volume version. The specs say it delivers 20 -- 25% more volume than the stock pump which I think would be better to have in the long run. While I was looking at pumps, there was a high volume, high pressure pump listed as well. What do you guys think about the high volume/high pressure pump as a replacement? I was thinking it might be a problem with developing leaks down the road due to higher pressure. I just want to keep the pressure up as the engine gets up in mileage. Any help on this would be greatly appreciated.Dave
