74 620 4x4 dana27 to '83 toyota axle swap


Recommended Posts

YoYo

I finally made an account after creepin around for a while because it is time to start fixin my 620.  The truck had a Dana 27 axle in the front and it was done kinda funky, a steering arm snapped and now im ready to throw a bunch at it and put on toyota front and rear axles.  I am going to put a high steer on it, a trunion bearing eliminator, v6 4runner dual piston calipers, land cruiser rotors, and more to come.  I have a chunk of the parts and the rest of them should be coming this week.  I will try and get some pics up tomorrow of the trucks undercarriage, the toyota front end, parts etc.

 

correction, I can't figure out how to load the pics, any advice and Ill bring yall pics......

Alright so day one on this project went great, we got a lot done and are mostly done with the axle.  I hope to get you some pics of the truck and what it has soon, but here is the axle build so far. Its going to be burly and ready to crawl when its done..........

 

 

Heres the axle with dirt and grease mostly intact,  I did a few hours of cleaning prior to this pic, but this is the starting point.

As a follow up, the picture that I posted earlier is this same truck before I bought it, so I thought I would post some pics of it in its current state.  It runs great and once this axle is built and thrown in and I put a Toyota rear axle it is going to be a different creature....

 

notice the pinner Dana 27 compared to the yota axle..

With some hunting around this forum I found a thread that a previous owner did on my truck that better shows why I am doing all this work on my truck.  there are a few upgrades since this thread, but its pretty close to the same.

Nice job on the Yota axle. 

 Jeez , we are going to have to start a Datsun / Nissan 4x4 section on this sight if we aren't careful.

You're plan is a good one and should work out fine.

Good looking 620.

The 'Yoda front is about an inch wider per side so I assume the rear is too. On my 620 it was so tall and had such large tires you couldn't tell it had the narrower H-190 Datsun axle in it. It was gaining a lot of weight though and the L20B really wasn't up to the job.
