1988 Grand Wagoneer
LS Swap, 1 tons, 37's
Selling my 1988 Jeep Grand Wagoneer. Bought February of 2014 as a 100% stock, rusted out Jeep that had sat in a garage for years. One part at a time, starting with the rear window all the way to it's current state has been done by me. The LS Swap was done spring of 2015 and the 1 ton swap was done summer/fall of 2016.
5.3/4L60E out of a donor truck. The computer, harness, throttle cable, rear driveshaft, radiator hoses, and even the factory exhaust were used from the truck. Yes, it even has the quiet stock GM muffler, but no catalytic converter however since it is greater than 25 years old, it is emissions exempt. The engine mounts are made by Novak Adapt, stock GM transmission mount on the stock Wagoneer transmission cross member. There is a clocking ring helping to raise the NP241 transfer case which came from a 94' Silverado. Stock GM driveshaft has been shortened and rebuilt and the front shaft is the stock shaft from an 83' K10. I did the wiring harness modifications per instructions on www.lt1swap.com including building the fuse box and OBDII port. I've never had the check engine light on, but if it did you can check the codes just like any new car. The gauges are made by Dakota Digital and are Wagoneer specific. These were $700 alone but we're needed for the digital speedometer and cool features such as 0-60 times, 2 trip meters, a tachometer, and several other functions that the original analog gauges could never do. Finally, the radiator is an aftermarket Full Size Jeep unit with electric fans all controlled by an adjustable fan controller. No manual switches or forgetting to turn on the fans. Truly user friendly. At the time of the swap, with a 4 inch lift and 31" tires I was averaging 20 mpg highway. Even with the 37's and 'tons, it can still get 16-17 mpg highway.
The axles are from a 2000 F-250 Super Duty. It's a Dana 50 front axle and a Sterling 10.5 rear axle. Both axles have 4.10 gears and the rear has a Detroit Locker. Both axles do need pinion bearings currently. The front axle has new calipers, rotors, pads, wheel bearings and u joints. The ball joints were previously replaces and were still tight so they were left alone. It uses the F-250 tie rod but the drag link and track bar are both 1.5" .250 wall steel tube with 7/8" Heim joints in the drag link and 3/4" for the track bar. The lower links have 1.25" heim joints at the frame with bushings at the axle for a better ride and the upper arms are 7/8" Heims and bushings. Both upper and lower links are 2x2 .250" wall steel. The front coil springs are 4" lift Rubicon Express Wrangler with 2" spacers to get the desired height. All the frame bracketry including the coil spring towers are from Barnes 4WD. It also had Bilstein 5125 shocks with firm dampening on all 4 corners and a Currie Antirock sway bar in the front. The rear uses GM 1500 leafs with all new poly bushings and is shackle flipped for the best possible flex. This set up rides GREAT for a 6,000lb lifted truck. Washboard dirt roads at 55mph are like riding on pavement. O spent time with different shocks to dial in the suspension and you will be very pleased!
Other things to mention, the front fenders were off a junkyard Jeep since mine were originally rusted pretty good so the darker grey doesn't match. I replaced the lower 1/4 panels summer of 2015 but the rocker panels currently need replacement. The floor was also replaced fall of 2015 and sound deadening was installed throughout the Jeep including in the roof. The headliner is done with plaid flannel for the ultimate classic Jeep feel. The front door window tracks have all been replaced as well as the window weatherstrip on all doors including the tailgate. The rear window lifter assembly was replaced as soon as I bought the Jeep and is constantly lubed to make sure it continues to work flawlessly. The carpet is indoor/outdoor stuff that was installed when the 1 tons were done because of the new rear inner fenders. The wheelbase was stretched 5" to allow for rear fender trimming without getting into the rear door. When I did this, I also widened the distance between the inner fenders from 45" to 50" to allow you to carry full sheets of plywood or whatever that is 4' wide.
The tires are 37x12.50x17 BF Goodwrench KM2 Mud Terrains. These only have a few thousand miles on them and they are mounted on 17x9 Raceline Avenger wheels with 8x170 pattern to match the axles.
So to recap, it needs pinion bearings, rockers, and paint work. I also have the material to trim the fenders in tube and build a cage over the engine to go to the spring towers if you'd like. This is just all stuff I never got around to and needs to be finished but I've lost room to work on it to finish the fee things it needs and want to see someone who will use it and enjoy is like I certainly have!
