How do I know if I have Dana 36 or Dana 44 gears? I am going to upgrade from 3:07 to 3:73. Will they fit into my housing or do I need to buy a new one? Is this something I can do in my driveway?:confused :confused
If you have the 3.07's you should have the Dana 44... (Assuming the 3.07's came from the factory)... I wouldn't recommend doing the gears yourself unless you know what you are doing... If they aren't set up correctly, you can easily crack a tooth on the gears and end up with a repair bill far worse than the bill to have a professional do the job...
Uhhh... you have 3.07 gears. Then I'll assume this is an auto trans? If that's the case then you would have the G92 performance option. I thought that was just 3.07 instead of 2.59 gears. But still using the Dana 36 rear end?? After all it was only a $50 upgrade... 6-speed came with 3.45 and the Dana 44.
So assuming you have an auto with 3.07 then you have a Dana 36 and yes you can put 3.54 ot 3.73 gears in it. And, no, don't do it in your driveway unless you've done this before. As Vettelt193 noted. You could easily do more harm than good. Pay a pro to do it and do it right the first time.
I am pretty sure the performance axle option, with the 3.07 gears comes with the dana 44... this is why everyone calls it one of the best options... who wouldn't want to pay the 50 bucks for a rear end that is a word better?... I don't have my blackbook with me now, I will have to look it up later... maybe someone else knows for sure though
