Straatmann Posted June 5, 2020 Share Posted June 5, 2020 Needing a little help identifying my axle and ratio, I’m assuming it’s a 35. Any help is appreciated. Link to comment Share on other sites More sharing options...
Straatmann Posted June 5, 2020 Author Share Posted June 5, 2020 It’s a 4.0 5speed if that helps at all Link to comment Share on other sites More sharing options...
jeeptec1 Posted June 5, 2020 Share Posted June 5, 2020 Model 35. (Dana 35) should have 3.07 with a 5 speed. The tag is unreadable in the picture. Automatic trucks normally came with 3.55/3.54 Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
Straatmann Posted June 5, 2020 Author Share Posted June 5, 2020 The only numbers I could make out it: 4770 324-1 Link to comment Share on other sites More sharing options...
89 MJ Posted June 5, 2020 Share Posted June 5, 2020 Post the VIN in the registry, they’ll get you the factory gears and a build sheet. Link to comment Share on other sites More sharing options...
Pete M Posted June 5, 2020 Share Posted June 5, 2020 ratio can be determined by spinning 1 tire around twice and counting the times the driveshaft spins. about 3 times is a 3.07 Link to comment Share on other sites More sharing options...
JustEmptyEveryPocket Posted June 5, 2020 Share Posted June 5, 2020 Jack up one tire, make a mark on the tire and fender (chalk works well), make another marker on the driveshaft and pinion snout. Then rotate the tire through two full revolutions counting how many times the driveshaft spins around. This will give you a rough ratio. The only options (unless aftermarket work has been done) are 3.07, 3.55, and 4.10. Maybe 3.73 was an option but I personally have not come across that one. Or pull the cover and count teeth. This will give you the exact answer. Link to comment Share on other sites More sharing options...

Pete M Posted June 6, 2020 Share Posted June 6, 2020 the ratio won't always come up since a lot of AMC info was lost before it could be inserted into Chrysler's computers. But I can say with confidence that it came with the 3.08s from the factory. that doesn't mean it still has 'em though. anything can happen in 3 decades.

So you can't know for sure unless you jack up a tire and count driveshaft spins or remove the cover and count teeth. Link to comment Share on other sites More sharing options...

Straatmann Posted June 6, 2020 Author Share Posted June 6, 2020 Everyone was right, almost 3 turns exactly. Link to comment Share on other sites More sharing options...
cruiser54 Posted June 7, 2020 Share Posted June 7, 2020 You can also remove the rear cover and read the numbers on the ring gear. Probably needs a lube change anyway...... Link to comment Share on other sites More sharing options...
