89runner Posted April 11, 2019 Report Share Posted April 11, 2019 This will be a build recap initially and then hopefully be kept up as I make new changes to the truck. Link to comment Share on other sites More sharing options...
89runner Posted April 11, 2019 Author Report Share Posted April 11, 2019 Don’t let the decent looking paint fool you. I only had a few body mounts still holding on. I kept the frame and driveline from my truck and the body from another truck I was able to get on the cheap. 2 Link to comment Share on other sites More sharing options...
89runner Posted April 11, 2019 Author Report Share Posted April 11, 2019 I should also mention that the rebuild started in November 2014 with a goal of driving the following summer. Link to comment Share on other sites More sharing options...
89runner Posted April 11, 2019 Author Report Share Posted April 11, 2019 Next order of business was cleaning up the frame, removing the IFS and then sand blasting the entire thing to see what was left of the frame. Lets just say there were some weak spots... 2 Link to comment Share on other sites More sharing options...
89runner Posted April 11, 2019 Author Report Share Posted April 11, 2019 A friend had a section of frame from a southern truck that made repairing the front drivers side a little easier after finding nothing but holes behind the IFS brackets. 3 Link to comment Share on other sites More sharing options...
89runner Posted April 12, 2019 Author Report Share Posted April 12, 2019 The back section of the frame was so far gone it was easier to fix up a rear set of frame rails from another truck and splice in. I also replated the inside of the frame on both sides. 2 Link to comment Share on other sites More sharing options...
89runner Posted April 12, 2019 Author Report Share Posted April 12, 2019 New rear springs were a bit longer than factory. I simulated body weight with whatever I had lying around to check shackle angles, driveline angles and shock positioning. 3 Link to comment Share on other sites More sharing options...

89runner Posted April 13, 2019 Author Report Share Posted April 13, 2019 Added a second t-case reduction and replaced a noisey bearing in the transmission. This gave me two 2.28 reductions. 2 Link to comment Share on other sites More sharing options...
89runner Posted April 13, 2019 Author Report Share Posted April 13, 2019 Front axle received a full rebuild, truss, knuckle gussets, diff armor, hi-steer and new perches to accomodate pinion pointing at t-case output. Knuckle ball welds were cut and rotated to maintain factory caster. Differential was regeared to 5.29 so my little 4cyl could turn the 35” tires. 2 Link to comment Share on other sites More sharing options...
89runner Posted April 13, 2019 Author Report Share Posted April 13, 2019 Rear axle got a full rebuild as well. New backing plates, all new bearings, diff armor, spring perches, rear geared to match the front and a lockrite locker. I even added new park brake hardware so I would have a functional park brake for more than a couple weeks. The rear pinion was also pointed at the t case as the drive line was too long and the wheel base too short. A machinist friend helped to build a custom set of driveshafts, both with double cardan joints at the t-case. 2 Link to comment Share on other sites More sharing options...
sar4x4 Posted April 13, 2019 Report Share Posted April 13, 2019 Will you need to add a new, higher, fill hole in the diff? The factory one might be more of a drain! lol Link to comment Share on other sites More sharing options...
autumnwalker Posted April 13, 2019 Report Share Posted April 13, 2019 This build is excellent! I enjoy watching the progress. So much work put into this truck. Link to comment Share on other sites More sharing options...

Until i have to pull the third again I just park on a steep bank to finish filling. 1 Link to comment Share on other sites More sharing options...

I could have saved a lot of time if I started with a decent frame but I didn’t have the time or cash for one from the states so I just worked with what I had.

89runner Posted April 13, 2019 Author Report Share Posted April 13, 2019 I had a piece of 3/8” plate bent for my crossmember/belly pan. It tucked the driveline up a bit and with the longer trans/tcase combo I had to modify the crossmember a bit to clear the rear driveshaft. I went with all through bolts on the new crossmember mounts as I would rather be able to just cut bolts off if they seize. 2 Link to comment Share on other sites More sharing options...
89runner Posted April 13, 2019 Author Report Share Posted April 13, 2019 My replacment body had seen some abuse and there was mud caked on everywhere on the underside so I gave it a good pressure washing. The tunnel was already modifed as there was a v8 in it at one point in its life. If only back to the future had a hovering 4runner! 1 Link to comment Share on other sites More sharing options...

89runner Posted April 14, 2019 Author Report Share Posted April 14, 2019 The tan paint was easy to sand off since the previous owner did a rattle can paint job without prepping. I replaced the rotten bits and tried to knock out some of the bigger dents. The rocker panel, a and b pillars and roof were pressed in quite a bit on the drivers side. The rocker came back pretty easy with a big hammer from the back. The other areas were hard to get at due to multiple lays of steel so I didn’t get fussy as I was leaving the other character marks on the body. I also had to shim the door hinges with 1/4” plate to line the doors up to since the sheet metal behind the hinges had been pushed in. This body had to have been on its side if not its roof before I got it. 1 Link to comment Share on other sites More sharing options...
89runner Posted April 14, 2019 Author Report Share Posted April 14, 2019 Once the body work was done I landed the body on the frame to make sure everything lined up since the frame work had been extensive and all body mounts were either cut off and replaced or rebuilt. The body also came off a pretty twisted truck but everything lined up and I only had to make 4 plastic spacers up for front and rear corners. 1 Link to comment Share on other sites More sharing options...
89runner Posted April 14, 2019 Author Report Share Posted April 14, 2019 The shop wasn’t big enough to paint the truck with all the panels off so I completed it in two stages. The body was first then all the panels second. I used a Ful-poxy primer, then rocker guard and Ful-thane single stage paint. I went from primer to paint in the same day as I wasn’t sanding anything knowing this was a budget paint job that would be scratched up anyways. I kept the floor wet and the doors cracked. 1 Link to comment Share on other sites More sharing options...

89runner Posted April 14, 2019 Author Report Share Posted April 14, 2019 Before I even got to paint the other panels I geared the truck up so I could drive it around the yard. I kept the harness,computer and injectors that came with the 86 body and it fired up without hesitation. The engine was the only thing that wasn’t taken apart in this rebuild. 1 Link to comment Share on other sites More sharing options...
