\'73 J4000 anything good?

I sware i put this post up eariler and it disapeared.

I've found a '73 j4000 sitting in the weeds. It's got a 360, auto trans, closed knuckle front, 5 lug wheels, and what looked like a centered 60 rear. I only looked at it for a second so i could definetly be wrong. What's the chance it has a 60-3 5 lug 60 in the back? Could this jeep also have a rare turbo 400 dana 20 combo or is it a q-tec. What gear ratio is in this jeep, i'm guessing 3.73's or 4.10's? Did i find a jem in the weeds or shoul i not touch it with a 10' pole.

I think 74 was the first year of the quadratrac in the FSJ's so you most likely have a TH400/dana 20 there. The rear is either a 5 lug dana 44 or 60. The front if closed knuckle is either a dana 27 or a hinged dana 44.

The J4000 was the one ton, I beleive. So the rear could definitely be a 5 lug 60.
And the turbo 400/dana 20 combo was used in the Commandos for the whole run. [img]images/graemlins/grin.gif[/img]

Do you have a price from the seller?

Already stated, someone will buy the 360.

Stop talking about it and be sure what you are looking at.

Good Luck,

Re: \'73 J4000 anything good?

id snatch it up if i were you, i found a 73 or 74 j4000 in a field about 8 months ago (been sitting for 5-10 years) with a 360/th400/q-trac and after a few hours of messing with the engine and redoing some wiring that 360 fired right up and it now powers my 76 cj7 without a problem, and i sold what parts i didnt use... i was able to pick it up for 200 bucks

oh, and the j-4000's came with both rear axle's, the 44 and the 60 it just depends on the gvw or something, like i said mine had the 44 with 3.73 gears but ive seen a 72 with a higher gvw and it had the 5 lug dana 60 in the rear with 3.54 gears with the 360/th400/dana 20 combo
