So regarding the thread name, Jeep Stuff is what the Jeep has become named. It was wrecked and totaled by insurance. I “bought it back” and began working on the upgrade rebuild, early in April. Working on it nearly all available hours, I would simply tell my 3 children that I had to do jeep stuff. They even began asking me if I had Jeep stuff to do. Thus it shall now be known as Jeep Stuff.

This is attempt 2 at this post. Hope it doesn't go wonky on me again!

Here are some pics of the damage. This is where I had Copart drop it off since its the flattest part of my property. Insurance was a battle after they deemed it a total loss. After 3 months, I was forced to invoke my "appraisal clause" since they refused to budge from their original offer. I paid a local licensed guy $300 for the appraisal. He went to the vehicle, photoed and documented everything about it then used that info to draft a report. He sends report to insurance and takes over the negotiations with their appraiser. They settled at $2,300 more than the original offer. Please remember that. NEVER TAKE THEIR FIRST OFFER!!! Also I never told them I wanted to keep my vehicle until after the negotiations were over. Then I sprung it on them!

Next was tear down.

Then reassemble. I sourced the hood, grille, and fender from a local jeeper a few minutes from home for just $300! Pulled radiator from that blown up yellow jeep.

Little hard to see in photos but the Dana 30 is toast! Broke the steering knuckle, crushed all four rusty control arms, bent steering assembly, and curved the passenger side of the front end, bent shock, slight bend on the sway bar, creased my rim.

Then it was on to the axle replacement. This is the part that starts becoming exciting and stressful. The yellow jeep Dana 30 is 4.11 gears. Red jeep is 3.73 so that easy swap wont fly. I'm not about to have a 2x4 jeep. Not this one. Not ever! Drop that bent front end and start to overhaul.

This is the new front end. Yes, you are indeed correct. The is in fact a YJ. Crazy, I know. The 3 months battling insurance crooks allowed my crazy ideas to take root and grow! I own most and have access to the few job specific tools to do a re-gear on that 4.11. Never done one though. priced a ring and pinion pair to match the red jeep. then thought if I did re-gear than I need to step up to right size for the 33" Patagonias I'm running. that quickly became more than I wanted to do when also considering the existence of this YJ.

A guy I worked with last year told me his father in law had a couple jeeps in his yard that he wanted rid of. The holey bucket of rust was a deal of a life time! The new front end is a high pinion Dana 30. Since I had to fab mounting brackets to convert it to the Tj, I figured I might as well do that with a truss kit. why not, I'm a welder by trade!

His son delivered it my paps House and onto that trailer. Paid $200 for the jeep and tipped truck driver $40. It's going to scrap very soon so some of that will be recovered. Yep, dumped it right onto the trailer from the flat bed. Cant roll it onto a trailer with out axles under it! Admittedly, this did make it slightly harder to get both axles off.

Don't worry, I wasn't just buying HP Dana 30. That rear end was the real purchase! Ford 8.8 Both geared in 4.56 But wait, there's more. That 8.8 is also carrying an ARB air locker. Right, why else would I dump the Dana 44 off my Rocky Mountain Edition. So now I've got a second Truss kit to sort out.

Ok now the rest.

Talk about stress. I was really sweating the placement of all the brackets on that 8.8! I measured, measured, drew it on paper, remeasured, layed it out on the 8.8, measured, remeasured, and sent it! Those things are heavy. there was no putting them side by side or moving the 8.8 to the jeep. My detached garage is around the back of the house. just wasn't gonna happen. It was a feat getting it up onto that horse by myself!

All along I was sort of planning to re-use the axle that was already with the 8.8. Oh, almost forgot. I put a SYE too. was gonna cheap out and run the used axle. Came to my senses and than began stressing the timeline and ordering a Tom Woods replacement driveshaft. Knew I had to get it onto the Jeep to measure for new shaft. Finished and coated the rear end and realized I was only half way to mounting and measuring. Like I was just gonna throw it on and measure but hadn't considered that it needs to be sitting on all the rubber, rear and front, to properly measure! Silly me.

Allow me to take this time to explain the timeline im stressing. Got jeep back early April. Know there's a great deal of work to be done. Also know that the Bantam Jeep Fest is June 13-15. The jeep fest that happens at the birth place of jeep! The jeep fest that's only 25 minutes from my house! I cant miss it again this year. I went last year in that crap yellow 4 banger but was to cheap to pay full price for 2 hours on Sunday! Praise God for that. That jeep blew a hole in the block the following morning on the way to work.

So I got the rear end onto a kreeper and shoved it aside for now. Went to harbor freight for an overhead hoist then started on the HP30. Remember now, the rear hasn't been moved to the jeep so I'm still stressing measurements and angles and placement. Also keep in mind that the front end is toasted and bent so it does not offer a lot of confidence of measurements and angles. Had to squeeze under the yellow jeep a few times to try that one too.

Here is where trussing the HP gets interesting. The guy who cuts the truss kits tells me he believes that his kit will work with some cropping and chopping. This burnt up a couple evenings of the time line, trying to alter and seal the CAD box in a manner that will then allow me to crop the truss kit to fit. Also note, the 2 piece passenger axle shaft had previously been replaced with a single shaft from an xj. didn't need the CAD so I cropped it down flush with the outter CAD housing for strength. good bit of chopping and grinding to land at this shape. that opened the top of the box like the face so they both got sealed off. then I learned about the respective axle seals and opened it back up to do stuff. long story short, I put a shaft seal on the tire side of the CAD box, it already had a different one on the right side of the diff. yes, I'm aware that there isn't a machined seal surface on the shaft there. trust me when I say it will be better than the gaping open end that it previously ran with.

Sealed it back up and kept going. finish the truss kit and get a coat of sealer on it.

If one locker is good than two has to be better! Since it was out and on the bench I figured no better time than now. Had a terrible scare on this one!

As you see, one did not cooperate. I was over torquing them. oops! Not the sort of thing to do a rushed spec search for. More praise to God. I heard it break. after much consideration, I backed it out. then it broke off, but left 1/4" of thread exposed to grab with pliers and remove!
New bolt, right spec, crisis averted! got it back in and got it coated.


Now I'm stressing putting these in by myself. called a buddy near by and he came to assist. after some hours of work, they were finally in!

What else am I forgetting.

After I got both axles under the jeep, all springs and shocks in place, all control arms bolted, I got the rear track and pinion angle as close as I could on a slightly tilted driveway. Visited Tom Woods website, spoke to a rep ion the phone, measured yoke to yoke then called back to order my 1310 double cardin driveshaft with flange for the 8.8 swap! The rep, Troy, was great to talk to. Naturally, I inquired about some swag or stickers that might be included with purchase. He said stickers are included and then asked my shirt size to throw in a shirt also!

Now I can finally breath again! oh yeah, the 8.8 diff cover. Break-in on the front locker calls for 600 miles. I've only got front wheel drive. This might work, except that I can't add gear oil to the rear cause the original 8.8 diff covers don't have fill holes. The front fill hole didn't even look worth trying. I ordered a Cavfab HD cover for the rear back when I was working on the rear truss kit. Lead time on their site is 2 weeks from order to shipment. At this point the drive shaft and cover should arrive a day or two from each other, but just a week before Jeep fest on the 13th. Then I need to clock 600 miles in a week. uh oh.

Now I'm considering finding the right place on the original cover to drill and tap for a fill bolt. Just to have more time for the miles while in front wheel drive. Though I am leaning away from the front wheel drive miles. I must be patient. come too far to screw it up now.

Here's the new muffler. Fits good and sounds good. Both of these jeeps had muffler issues. My jeep was always loud. Wife hated it and kids didn't like it in the school pickup line. Silly kids, I'm picking you up in a lifted 4x4 convertible. It don't get cooler than that!

With the shaft ordered, things could slow but just a hair. I'm still out there every available hour with the finishing touches. Got new extended front brake lines on the front and my wife laid the pedal for brake bleed. With all the brake lines finished I could finally start it up again to burp the coolant. that's done. the heat blows hot and the a/c is still cold too.

The winch. It ripped off the bumper during use back in November, prior to the wreck. wild story there. more Priase to God on that one too. Welded the mounting plate back on the newly cropped bumper. Made sure to run some hot and heavy beads this time! Actually wired in the included power throw switch too. red knob on the airbox.

upgraded my horn too, cause why not have a big jeep make big noise. haha Those horns are no joke. They are violently loud to the point where they cause static in your ear if they blow next to you! money well spent. I wired them on a separate button so the factory horn still functions also. my 6 year old daughter loves this new button!


IMG_6633.jpg



Beside the horn you will see the new home of the ARB pump. daddy is excited for these new buttons!

Anybody have any trouble cutting the tailpipe shorter? Any adverse affects like heating the gas tank ?

I'd worry more about the exhaust heating your shock up which could cause it to blow or leak. And if your pointing at the fuel tank you could have vapor lock from heating the fuel. I'd want it turned down away from both or exit in a more stock location if possible

Mine is turned down in front of my rear axle. Some say they get exhaust fumes when doing this but I haven't so far.
