Lucky 07 PreRunner to 4x4 Conversion

NB = New Braunfels. Between Austin and San Antonio.

 

Torqued the tc to flywheel, starter back on, pan bolts torqued. Front driveshaft cleaned up and installed. Built the crossmember. It isnt completely done - need to add the center section, but I'll tack that in before lunch tomorrow. My welds look like drunk dirt-dobbers. I'll grind them down and make sure fusion is good, then lay down some pretty beads. I'm getting close to the end.

 

Thanks makes sense now you say it. Throw it in 1st and manually shift it up

 

Almost done. I need 4 more driveshaft nuts for the front shaft. And I totally forgot about modifying or replacing the exhaust crossover pipe. Other than that I need to top off fluids and bleed the brakes






I ended up using a d-cab 4x4 rear driveshaft. I used some angle iron to make the relocate bracket that not only allows the carrier bearing to move back a couple inches, it also facilitates a slight drop. I only had mild vibration before the swap - we'll see how this goes.

 

Finally!! The truck will drive today. One of the last pieces to this project, Exhaust... Getting a piece made this morning that routes around the back of xfer case instead of the stock design that goes under it. Here's the exhaust mounted with the crossover cut out.






View of the twin stick FJ case shift cables. I still have to fab the mount that will secure the cables and shifters on the inside.

Pass through

 

Sub'd. Awesome thread OP. Cant wait to see the finished product!

 

Didnt get the exhaust done today, but I drove it anyway. So far so good.

Final pics and PreRunner de-badging tomorrow.

 

Its pretty smooth, but short throw, so it feels a little harsh.

 

Still dont have my crossover pipe. Should have it tomorrow morning. Everything else is going pretty good and is functioning as expected.

Heres what the cable shift setup looks like on the inside. The shift levers are still raw - I'm going to round them out and polish a little and thread the ends for shift knobs.





Both shifters come up through the right side cup holder.






Heres a support I added to the twist lock cable controlling my ADD.

 

A couple more of the cable bracket I fab'd up.

 

Wow this pretty badass. A complete list of parts would be great for members thinking of doing this. I don't have the free time for this so I'd probably trade my truck in for a 4x4. But great job on the conversion

 

A complete list can be found by searching. Quite a few threads on it already.

 

Shifter assembly looks badass, nice work!

 

Exhaust done. NIcely tucked up out of the way.

 

Have about 300 miles on the truck since putting it all back together. All good. No leaks, creaks, vibration from the driveshaft or shudder when taking off. Had a chance to mess with the center console today. Me and the dremel salvaged a cup holder. I'll work on the shift levers and boots this weekend, along with some wiring to get the dash indicators for 4wd, 4lo. I also need to wire up my elocker.

 

The 6061 stock I used for shift levers is pretty easy to shape - going to cut some threads later today. I decided to go with stock FJ Cruiser x-fer case shift knobs. Their pattern matches the dimple texture in the tacoma. I had 1, another picked up on ebay. I popped the J-pattern disk off the top of the shifter. Havent decided if I will replace them with my patterns or put in a blanks.

I put a small bend in the left shifter, leaning it towards the driver side, the levers with knobs will definitely clear each other.

Hi-Lo lever is disconnected from its linkage right now, so I had to hold it up in the position it will be in.

 

Very nice!

 

All thats left is the transfer case dash indicator lights and diff lock light, my second FJ shift knob that isnt here yet, and a twin stick boot.


AS far as the wiring, according to the FSM, the C10 (right side) connector on the instrument cluster has the wires for 4x4, 4Lo and Diff Lock lights, located at pins 15-red wire, 16 Brown-white and 14 Blue-yellow, respectively.

Since my truck was a prerunner, open diff truck, it doesnt have the 4wd or elocker ECU's and I didnt buy either of them for this conversion.

No problem on the locker as far as engaging and dis-engaging, I easily got it wired up per 12voltguy's diagram using a DPDT on-on switch. I actually used a DPDT on-off-on 7 post switch, with #7 post assigned to the light on the switch. I dont really care if the switch lights up when locked though, I'd prefer to have the dash indicator. I'm going to try to take Blue-Yellow from the locker position indicator switch and run it to Blue-Yellow on C10-14 on the instrument cluster and see what I get.

The xfer case 4lo switch has 2 wires, White-Black and Yellow-Black. Similar to above, I will try taking Yellow-Black to C10-16 Brown-white and white-black to ground.

The xfer case 4WD switch has White-Black and Red-Blue. I'll try Red-blue to C10-15 Red, white-black to ground.

If anyone has any wisdom on the wiring, please share. I read in one of Wyatt's posts that they had to wire indicators straight to the cluster on Ray's prerunner conversion, but I couldnt find any posts here or on RST on how they did it.

Very nice work! I have most of my parts for the conversion, just need a shifter(s) and rear driveshaft. I am only into it $1500 so far and have a taco tcase to sell.
