1986 XTRA Cab Truggy
« on: Oct 01, 2020, 01:57:51 PM »
Over the summer I gave up on building a full tube buggy and wound up trading the chassis and some parts for this 1986 XTRA Cab with a flat bed.  It was pretty well setup with Alcan springs, Sky's Offroad SAS, HP front third, 5.29's/ARB's front/rear, 30-Spline Longs up front, what I believe is a 4xInnovations interior cage, Marlin dual cases with 4.7 main, PSC assist, winch,  and 37's on steel wheels.



I met the guy about halfway and then as soon as I got home I loaded it up to go do some mild wheeling and camping.

I met up with a buddy who had just finished up a 3 year long build on his Early Bronco.  Its stretched, on coilovers front/rear, caged, and fuel injected now along with a bunch of other neat little tricks.  This was basically a shakedown run for both of us and both rigs did great w/o any real issues.

The one thing I had noticed on that trip is that the E2000 external fuel pump mounted down on the frame rail didn't seem too happy having to pull fuel up and then back down to itself.  Between that and needing an emissions test (requiring a proper filler neck) I made a few changes.  I started out by building a pseudo headache rack for the flat bed.  I then used a remote reservoir shock mount to move the fuel pump closer to the tank.  After that I finished it up by mounting a filler to the headache rack.  In the end the pump seems much happier and the enviro-nazis gave me the pass.

Everything seemed all nice and happy in the Toyota world after that.  I quickly welded up some little tie-down brackets on the rear axle in time for another trip on a more challenging (though still fairly moderate) trail where the Toyota once again performed perfectly.  I was finally ready to just let my wheeler be and focus on my CJ6 diesel project when FB Marketplace popped its little head in and ruined it all.  I scored a silly smoking deal on a set of 4 aluminum bead locks with decent tread Nitto K-Spec stickies that I couldn't turn down.  SMH, time to go down the rabbit hole lol.

With a trip to Penrose, CO to run Indy/Patriot/Liberty trails I decided I should probably go through and do some checks/maintenance on the truggy.  I pulled the front axle apart and verified that the ARB and gears were in good shape, also verified that it did indeed have 30 spline Longfields in it.  I added some harnesses, made the doors removable and converted them to manual windows so as to prevent caving them in.  I also added some roll bar padding, retorqued and locktited the studs into the hubs and knuckles, replaced some worn TRE's, installed chromo inner hub gears, and other little things.  Penrose isn't necessarily full buggy rated, but it is up there and now I was running arguably way too big of a tire for the Toyota axles so I wanted to make sure everything was tight and in good shape.



I literally got it all slammed back together the night we were heading down.  I just set up my sleeping pad in the bed of the truck and woke up to a nice sunset with my pretty little truggy looking over me. :D

The next morning after some instant coffee thanks to my Jetboil I unloaded the truggy and pulled the doors. Then we just kind of bs'd while waiting on a buddy to show up with his buggy. Once he arrived we dropped into Indy and the fun began.

After Mike showed me the line it was my turn to climb the exit out of Patriot.

All in all the truggy did awesome.  It climbed all the technical sections and worked its way through the trails with little interference from me.  It pretty much just creeped its way along.  The buggies could go much faster between the obstacles than I could, but I never really slowed them down as it was just making continual and steady progress. 



After the climb out of Patriot they wanted to drop in and run it backwards.  I opted to ride in the XJ based buggy as I didn't feel a need to just bash the Yota like that after such a win.  We then pulled back around to grab it, had lunch, and then dropped back into Indy so we could go out Liberty.  The trip was great and the little Yota impressed all.  Not to say it didn't make it out completely unscathed.  The second time down Bunker Hill I was too far left and scraped the cab a little.  I also got some rash on the bumper corners, my flat bed, sliders, and even a little bit on the driver side fiberglass fender.  Oh yeah, and somehow I still managed to bang the tiny front diff on a rock despite having about a mile under it with 40's.  Overall though it was awesome and just an overall fun trip. 



The truggy definitely proved itself and I was able to identify a few things I wanted to fix/address.  The first thing was brakes.  It has vented front rotors and a V6 master, but still the 12+8 front calipers and drums out back.  I literally could not stall it out in double low dropping down the bigger rocks.  As such I have ordered new rotors for the front (worn anyway), 12W V6 front calipers w/ pads, an FJ master cylinder, TG budget rear disc conversion, and stock solid axle front pads/rotors/calipers for the rear.



The other thing was axle width and steering, or lack there of.  The steering stops on this thing are extended out over 5/8" over what my buddie's stock 83 has, probably to keep things from rubbing.  It also came with 3" spacers on each side up front.  Even with 4.5" BS wheels this makes for some cruddy steering angles.  As such I've got a TG +5 housing on the way that'll keep my width where its at but let me lose the spacers.  I'm hoping this lets me adjust the stops in significantly and helps in the turning radius department.  I do also have a set of 1.5" spacers for the front that will help push it out to 64"+ WMS for a little extra stability.  To round out the front axle I'm replacing my Marlin Crawler high steer arms with FROR keyed ones that have the larger pins, 25mm bearings, and beefed up bottom caps.  I'm also replacing all of the knuckle and hub studs with ARP's.  So now its torn back apart in the garage as I await parts and hopefully a trip out to Moab at the end of the month as well as hitting BV Carnage when my buddy gets back from his deployment.

Bit late of an update but I did get everything swapped over. The new TG +5 housing showed up quickly. I took all of my wheels/tires to work and used the big tire machine to dismount them so that I could flip the tires around and get the better tread on the outside. I also got the brakes installed on the rear axle, rebent the brake lines, and added a little weld on pumpkin guard. One of my stock rear shafts was bent at the flange so I swapped it out with another one. I have since ordered some Yukon rear shafts and will be installing those at some point for extra peace of mind.

I am having some issues with the disc brake conversion out back I need to sort through, and I definitely want to add a parking brake back in. I'll probably do a t-case mounted one, but I'm not sure yet.

Up front I got the TG housing installed with the new inner shafts. I tore apart the 10+ year old OG Longfield birfields to clean/inspect them and they looked great still. The keyed steering arms with 25mm trunion bearing pins were worth the wait. They installed super nice and between those and the ARP studs I'm pretty confident that I won't have issues with my steering arms or the knuckle bearings. I did keep 1.5" spacers (had 3" spacers with the stock housing) but the steering angle is much improved and nothing rubs up front when flexed and full lock. I did add steering stops back on after these pics and have them set at right when the TG Trail Safe wiper seals make contact with the axle tube. I unfortunately don't have any pics of it on the trail as I didn't take any, but other than some quirks with my brakes and all of my bead lock ring bolts coming loose everything seemed to work well. I do want to shorten the WB a bit and probably ditch the internal cage for an exo cage. Rework the flat bed at the same time, possibly link the rear, yadda yadda yadda. You know how it goes. It just never ends.
