i= you can install it yourself with a jack,jackstands, blue loc tite, basic hand tools + torx bits, and about 3 hours with a buddy....2 if youre good.
What exactly does that mean burnruber? If youre good.... Does that mean if I help a little old lady across the street today, I would be able to do it in 2 hrs?
Or does it mean if I don't drink any beer while I'm doin it, I can do it in 2? I have a story for you, I used the Navy auto shop to do mine.... Air tools, full lift, and a paid helper to come to my assistance...... had it done in about an hour and 3/4....
SWeET Biggest problem was gettin the rotors off, had to bang on em with a rubber mallet. Everything else? Cake.
As to the question at hand? I agree with burnruber..buy a GT takeoff for idk $800 or $900 or so, with either 3.73's or 4.10's if you have an auto, and install yourself. Best way to go in my opinion. I have no fear that my n/a (or power adder in the future) 4.0 will EVER challenge the integrity of my rear axle. Makes me sleep better at night. Couldn't say that about the 7.5
Plus, if you are dilligent and search craigslist or ebay, you might find a screamin good deal on a takeoff rear end. Put your money under your pillow bud, and save more till you have enuf to do it right. That is the ONLY smart thing to do.
