Hello, everybody! I posted here a while ago searching for a new TJ/LJ. I stumbled across a very clean example in New England, that I considered acceptable given the price and location. It's a 2005 LJ, 113k miles, bone stock, very well optioned with premium appearance, power rear view, two tone seats, cruise control, Dana 44 w/ LSD, 7 speaker setup, brand new Bestop- it's just set up to be the perfect daily. The only area of any rust/rot is the inner windshield frame, and up around the rear shocks. I just had it up on a lift, and you could eat off the frame. Inside is good, too. I paid $9k, and being in the rust belt, I'll accept those things. Windshield frames are a dime a dozen. I'll post some pics of the whole rig once it's all set up & cleaned. The ones I attached are from the marketplace listing.

Anyway, there are a few concerns I have right off the bat that I want to address before I have peace of mind on my long road trips. I figured, even with my research I've been doing, there's nobody better to ask directly than the folk on this forum. With that being said, my concerns are as follows:

  • There is an excessive amount of backlash in the front driveshaft. I have an 01 TJ, and I am almost certain this has much more backlash than that. Both have Dana 30 front axles. Is this reason for concern, or is that considered normal?
  • There appears to be a whine coming from the transfer case, especially in 4WD. Again, my 01 TJ does the same, and has for the 9 years and 60,000 miles that I've owned it. Is this just normal, or acceptable?
  • Cruise control doesn't work. The light comes on, but the speed won't set. Occasionally the light will come on, immediately go off, and won't come back on until I restart the Jeep. I know, it's an old Jeep, it doesn't NEED cruise control - but I am making 1000 mile round trips every month for the next few months while I move to Canada, so it certainly helps. What would cause this to not work, and could the next issue on this list be related?
  • The high beams don't work. I had the original lights still in there, so I figured maybe they happened to both be burnt out. Uncommon on high beams, but I've seen weirder. I swapped in my lights off my 01 TJ, and they still didn't work. As an added bonus, I broke a wire out of the headlight pigtail. Woohoo! What might cause the high beams to not work? Fuse maybe?
  • I've heard of people drilling holes in the frame underneath the control arm mounts to help drain moisture. Is this recommended? I've heard mixed feedback.
Otherwise, this thing is great. Drives as straight as an arrow. Tires have 200 miles on them, 31x10.5r33, no lift. Owner bought it in 2017 out of state, and only put 4,000 miles on it between then and yesterday. Older gentleman, very nice guy. I pulled the rear driveshaft out to try and narrow down the vibrations, but it's pouring rain and I didn't wanna go down the highway at 65 to recreate the vibe in a front wheel drive Jeep right now, so that's a tomorrow project.

I appreciate any feedback, and I am glad to be back in the Jeep community. I had parked my TJ for roughly the last 5 years as the daily because I purchased another car. I missed the Jeep all the time, so I'm ecstatic to daily an LJ!

Can’t help with your questions, but have some of my own:

What is “power rear view”?

And are you sure about the tire size?

Check for play in the splines in the front driveshaft. If there’s play just replace the driveshaft. If not rebuild it.

Check the TCase fluid level. Fill to the bottom of the fill hole.

Check the vacuum tubing and boots from the cruise control module. Often there is a leak. The line is likely brittle. If so it’s likely original and needs replaced. Local parts store.

Yes, drill a 1/2” hole behind the front control arm frame bracket and in front of the rear control arm frame bracket. Then paint the raw steel.

Whoops. It’s been a long day. 31x10.5r15.

My other Jeep is 33x12.5r15, so I was probably thinking about 33s when I typed that out.

The power rear view is the mirror that has the reading lights, temperate, compass, and is auto-dimming

Thank you a bunch, you just gave me my list of tasks for tomorrow!
 
PCM original?

Lot of your rubber parts are probably at the end of their lifespan. Motor and transmission mounts. Axle vent tubes. Rubber inside the crank pulley. Valve cover grommets. To name a few.

Do you need a massive bumper, tire carrier, rack carrier, Jerry can carrier for all those long road trips? $100 and I’m close to Ct AND will be driving through your state tomorrow 😁

Yes, original PCM. Everything is original.
 
Check the 3 pin headlight plug. It is very common for the overloaded wiring to get hot and the insulation will shrink back. When that happens, the wires can touch and prevent one or both of the light modes from working correctly.

I found that one of the wires going into the pigtail is broken. The headlight does not work, at all. I wonder if that also causes the high beams not to work.
 
But, it’s heavy.
One of my favorite things to watch was the scrambling by conventional sellers of heavy steel Jeep parts after we introduced the first Savvy aluminum parts. One notable seller of a steel gas tank skid described it as nearly 90 pounds of heavy steel goodness. That changed in very short order to something along the lines of strong and heavy duty with no mention of the severe weight penalty.

I'm sure I found that far more entertaining than most did. The other thing that was very bad is one of the first great steel gas tank skids was written up in a magazine and while it was meant to promote how great it was, there was an error which listed it as 1/8" which effectively killed the company for being idiots and making something too light duty to work. It was actually the correct 3/16". I had several of them and chatted with the owner of ACF many times about it. He was not happy.

This conversation just made me realize 20 years ago I bought my TJ with a Tomken Machine gas tank skid, which is likely a 90 pound hunk of steel. I never really thought about it until now.
