project: Trail Grenade


Recommended Posts

ok so ive owned this thing for like 5 years, it used to be the plow truck but it hadnt been used in 3 years. so last spring i decided to dig it out of the weeds, put some bald 31s on it and use it for trail cutting at my house. ive beat on it for the past year and the renix 4.0 and pukegoat 5spd are still holding up fine.. well a month ago i broke both front shafts at the same time..

 

so with rausch creek opening 1200 acres and my love for trail cutting i decided to make it a little bit more rock reliable. so i pulled an 8.8 with 4.10s at the jy and at the same time i pulled the gears out of a 4cyl comanche. i installed the gears in a hp non disco 30 i already had with 297 shafts.

then i started bulding the 8.8.. i tig welded the spider gears up first and then

i bent up some tube for a diff guard and welded it to the stock cover after i plated the lower lip

 

then i built a removable pinion guard for it

 

and fabbed my own u bolt eliminator spring perches that use 5/8" bolts and have integrated bump stop pads

 

so once my 8.8 was ready to go in i decided that i didnt want to put it back in sua because of the crazy loss of clearance.. but my leaf springs were in awesome condition and would have given me like 8" of lift if i put them spring over.. i decided to inboard my leaf springs to the inside of the unibody rails and up about 5" i fabbed new spring pockets on some stiffeners and welded them up

 

next i built new shackle boxes and set them up using some 1.5 shackles to get a nice nice shackle angle

 

while i was working on the back half i recessed an xj gas tank down in the floor in the front of the bed to get it up out of the rocks and protected

 

right now it has beat 3" coils in the front and its sitting level

 

i got some 33" dunlop mud rovers with like 75% tread in trade for a gas tank skid i built for some one

 

its a work in progress and needs to be finished for my trip to rc the weekend of may 1st.. i have a lot of work to do still

 

fab front diff guard

fab front stiffeners and bumper

fab new crossmember and flat belly

fab boatsides

fab rear bumper

fab rear shock mounts (upper and lower)

install dual brake booster and zj prop valve and all new brake lines and hoses

install front shocks

install new u-joints

wire up electric fan to a switch

install renix sending unit into tank (so my gas guage works)

figure out exhaust

and a bunch of other random junk

 

ill keep updating as it comes along

i don't know about those UBEs but i love the pinion guard.

prolly should have noted the top plate is temp. for mock up purposes and will be replaced by 1/4 or 5/16" when its wheeling time... antidisestablishmentarianism else arent u sure of?

 

well i wasnt sure of the thickness of the plate...so nevermind then keep up the good work.

So i have recently started another major project on my comanche. I got sick of working around and fixing the stock bed and "frame" behind the cab, and decided to cut the frame rails flush with the cab and start fresh. I have a trip to rc planned for the weekend of october 29th, therefore it will need to be finished up and ready to wheel by then. With that said, on to the plans and progress.

 

stock spring soa, inboarded, flipped

stock wheelbase 113"

14.5" white body's

5" frame "z"

my 8.8

rear crossmember with shackle mounts frenched

 

 

you can see here, it was a little tweaked

 

cut everything off behind the cab

 

cut and folded the pinch seam along the back of the cab and started working on a plate to cap the back of the cab, frame rails, and tie into the boatsides

 

the 8.8 pulled

 

cut some plates out to connect the cab cap to my already existing frame stiffeners on all 3 sides of the stock rails

 

tonight i got my rear crossmember tacked together

That's where I'm at right now, i hope to get a couple hrs in a day to work on it.
