I think I'm going to try this I have a 93 YJ with a 4.0 and no trans, T-case or axles and I have an 85 4runner that is rusted out. Stretched wheel base toy axles and dual cases with the Jeep 4.0 should make a nice rig.
has anyone gone any further than just thinking about it?
Kyle_22r is right again I have put a Marlin dual case behind a AX5 [G54/58 Toyota] Jeep trans by changing the output shaft and tailhousing from a Toyota doner trans.This can also be done to a AX15 [R150 Toyota].The Jeep auto should also work as long as the output shaft and rear housing is changed from a Toyota trans.In the past years, I used to get a lot of calls from Jeep owners wanting to go slow like the Toy trucks. Since I was so busy, I directed the calls to Mepco and Klune V.Marlin
i had been thinking of running the setup of my 4.7 I6 stroker, ax15 front half, toy rear trans case and output shaft, doubled toyota gear drive cases.......however, a friend of mine had the toy tranny and gear drive case behind a mild 305 ( if you check both motors when ran on the dyno, the 305 made less power and less torque than my stroker) he kept blowing the inputs on the toy case. So what i have sitting in the garage as of now.... is ax15, np231 crawl box(box4rocks) mounted to a Dana300 with 4.1 gears. I havent broke the input ever on the 231, and i dont think ill break a 300. I have been through ALOT of parts for the ax15, but replacing parts is cheaper than buying a nv4500 outright. Anyway, this will give me a crawl ratio of 224.19, which is alot better than my ratio of 47.9 as of now, with the ax15 and stock geared 231. The crawlbox overall length is around 8 inches, and the 300 is roughly 8 inches shorter than the stock 231 with the slip yoke. Everything bolted together is only about 1.25 inches longer than the stock 231 was. But since i am moving the rear axle rearward, then my driveshaft length is allright. And since you can flip the dana 300, it is possible to still us a driver side differential alxe in the front if desired, however i will be going with a pass drop axle. The crawl box can be used in front of anoher 231 tcase as well. Didnt mean to hijack the thread, or to turn any business away from marlin by any means....just wanted to let you kow of more options incase you are worried about running a higher powered engine in the future. And with the way the wheeling goes over here in the east....i need the power and the strength. I just wish marlin had a crawl box setup for the 231, so that i could buy it from him, instead of any others, bc i KNOW his setup would be better engineered than anyone elses
lots of people run marlins cases behind a lot bigger v8s than a 305 and have had no problems with strength issues
