Project Franklin (DD-Towpig-Expedition)


Recommended Posts

Alright guys, I've been looking for one for a while. Found a good 'un. Almost rust free Maroon 87 LWB 4.0 Auto 4x4 with 149k miles. Got this beast for the princely sum of $1k:

 

 

 

 

 

Interior is nearly immaculate:

 

 

Only found one rust spot in the usual spot:

 

 

Not too worried about it at the moment, the rest of the floor board looks good and solid under the carpet. I'll address is sometime later.

 

Well, I helped out a buddy and bought some wheels and tires from him and this is how it has turned out so far:

 

 

 

 

 

When I test drove it, it made the most terrible pressure cooker whistle. I did some research, tightened up the terribly loose intake manifold bolts and voi-la! No more noise. It has a couple hundred dollars worth of work left yet, but it runs great. It needs a wheel bearing it sounds like as well as an axle seal, but I'll get to that. It may also need some motor mounts as it seems to have something underneath contacting the undercarriage but it's not the exhaust.

 

It was overheating till last October when the PO put a new radiator, water pump, coolant tank, and fan in it.

 

Plans:

-Full tune up

-Decat

-Wheel bearing/axle seal/misc maintenance stuff

-Open loop cooling system upgrade

-Waggy front clip? Later pre 97 front clip?

-Bumpers front and rear w/spare tire gate on back

-Ladder rack converted to be a safari roof basket

-Hella 500s all over the place

-V8 ZJ coils, 1in spacers, Free 1.5in shackles my cuz is sending me

-Metric ton leafs if I can find them

-ZJ rear discs

-WJ brake booster/master cyl

-235/85/R16 Treadwrights on some solid steelies

-Snorkle

-Some tunes

-CB

-Winch

-Roll on rustoleum paint job in Desert Tan? Gray?

-Roll on Bedliner

-Full Grey interior swap with buckets/center and overhead console

-Maybe some sliders

-Maybe in the future, I'll buy a rearended 97up XJ 4.0 5spd and swap the motor, trans, entire front clip, doors and interior

 

I'll have the grill and front and rear bumpers for sale at some point.

 

Love it!

I washed the engine bay today and after that it started running intermittently rough. It would bog down on the highway and then surge back to normal. It also boiled over. Got it home, did some research, found that I probably toasted the TPS when I sprayed the bay, installed a new one and it purrs like a kitten. It was running a little rough before anyway, and the PO thought it was fuel related, but I figure the TPS was on its way out anyway. So, now it runs great.

 

Next thing to do will probably be some vents in the hood and a failsafe tstat, after which I'll do the wheel bearing/ujoint depending on what is making the noise and the pass side axle seal.

 

Edit: Desert Tan sounds good.

What kind of condition is the pressure bottle on the firewall? The Renix system you have is a pretty solid system, but it does have it's quirks. One of the most troublesome things is the bottle, as it becomes brittle and cracks, not allowing the coolant to maintain pressure. Another is bleeding the system out. That style takes a certain few steps after a good overheat or coolant drain to get rid of air pockets.

Yep. Park it cold, facing down hill. You want the back of the engine to be the highest point. With it still cold, pull the temperature sender on the back left corner of the head. (Remember that all left / right directions are given as if you are sitting in the drivers seat facing forward). Make sure the bottle is topped off. Start the truck and let it warm up until you start seeing coolant start trickling out the sender hole. Once it starts coming out, put the sender back in, and that will generally do the trick.

Make sure the cap seals on the bottle correctly. My XJ had a new aftermarket bottle when I got it and it kept boiling over,turned out the cap wasn't sealing right. I put in an OEM bottle and never had another issue.

I highly advice against this. I bought one once, it''s a gimmick..

 

They way they are designed, it has little hooks that grab the disc once the temperature reaches 210 degrees, not allowing it to close again, ever. So if the coolant ever reaches 210 dehrees it fails in the open position causing you to have to replace it. Problem with this is that 210 degrees is well within normal operating specs and can easily be reached on a hot day, towing or hauling heavy loads, mountain driving, etc. I bought mine in Columbia, SC on the way home from Florida, around the VA/WV border I hit 210 degrees and was essentially running without a thermostat from that point on. This was the third week of February, not very warm out, but I was cruising 80-85 through the Appalachians in my 6000 pound Suburban.

 

Just get a regular good quality 195 degree thermostat and stay as far away from the failsafe ones as possible.

Thanks! I like the Moabs, but will likely go with a 16in steelie in the future.

 

I'd like to go one inch higher.

 

I have a donor ZJ V8 but I've come to a crossroads:

 

5.2/autotragic or Mercedes OM617 turbodiesel/AX15?

 

The TD would be muuuuuch less of a wiring headache, but I already have the 5.2. The 5.2 would have more power, but the TD can be built to be an absolute torque monster while still getting 25+ mpg.

 

Opinions?

Well. I picked up the donor tonight. Franklin was a little angry with me by the time I got home. He was a little "hot" lol. In all, I made it with no hiccups. I guess I settled on the V8 swap since I've already got the thing and it only cost me $200 for the entire donor.

 

 

V8 swap, here I come.
