    '03 TJ Trans/T-Case Vibration during Acceleration

    "Slower than engine speed, higher than tire speed, roughly triples in frequency in 4LO" all sounds like it's either output-side of the transmission or input side of the transfer case. Input side of the transmission is always matched to engine speed, output side of transfer case is always...

    Arizona Tow Pigging Daily Driver

    Yep - even the best surge brakes are worse than electric brakes. The only part on that I might be a bit spoiled on is I've never towed with the specific combo of an aftermarket brake controller and a trailer with electric brakes. My WJ had an aftermarket controller from the original owner...

    New Cloyes timing sprocket (crank side) is too tight

    It's been going on longer than just a year, too. I bought a Cloyes set from OReilly in 2020 that had the exact same "crank sprocket too tight" problem. Meanwhile the Autozone set had a cam gear that wouldn't fit. Local Jeep dealer wouldn't even attempt to order one. Ended up mixing and...

    Arizona Tow Pigging Daily Driver

    Yup, can't argue with a solid copper license plate. My TJ still has three years to go.

    Arizona Tow Pigging Daily Driver

    Copper plates have zero restrictions other than 25 years old, and provide no benefits other than looking good. The emissions exemption requires classic/limited-use insurance, which doesn't require any specific plate type.

    Viair 88p on ABS tray - have a couple questions

    So far so good, but I also view it as "if it dies, it dies". If it ever does give up the ghost I'll redo it with a Viair actually intended to be mounted.

    Front differential leak, should I just redo the RTV?

    Thirded. They're reusable (within reason) and it makes future fluid changes much faster since you cut out the entire razor blade / wire wheel portion.

    Viair 88p on ABS tray - have a couple questions

    I have mine hard-mounted to the ABS tray but apparently I've never taken a photo of it. I bolted it down, I want to say I used at least one of the existing threaded holes in the tray. I also hardwired the power to a relay controlled by a switch in the cab, and cut most of the hose off to plumb...

    Weird electrical gremlin

    To be fair, I discovered this a couple weeks ago when I hooked the battery back up on mine while the grille was still on the ground.

    Weird electrical gremlin

    The ground at the front left of the engine bay is disconnected - factory setup is a ring terminal on a 10mm screw going into the back of the grille. That ground services the left front marker light, the washer motor, and the horn - I suspect with the ground disconnected, it manages to backfeed...

    NV3550 replacement shifter options

    The closest thing I have to a complaint about the B&M is that between the TJ and the Ranger previous to that, the only manuals I've driven for the past 11+ years have been generously described as "sloppy". So I've developed a habit of pushing sideways as I'm shifting (i.e. to the right when...

    Test AC Clutch / Compressor

    Probably had a poor connection at the relay itself. The clutch needs a decent hit of power to actually pull in. I went chasing down a similar rabbit hole on my WJ. On that I'd confirmed 12V at the compressor with a digital meter, but I hadn't checked with a real load, and thus wasted time and...

    Oil Filters

    The actual thread and gasketed area on the 51085 is the same as that, even though the overall can is much wider.

    8.8 swap questions

    You can "clearance" the stock tank skid with a large hammer, no need to shorten the wheelbase.

    Paint degradation

    My '02 has been parked outside in the Arizona sun for pretty much its whole life as far as I can tell. The paint is amazingly still sticking to the Jeep, but it looks absolutely awful on the hood, grille, and cowl. Easily the worst paint I've ever seen that isn't just flaking off in sheets...

    Best serpentine belt

    They did sell the whole division to Continental, and for a while Continental did continue making the Gatorback-style belt - but that stopped years ago. Any belt you find with that cut-rib design is going to be very old stock at this point.

    05 LS Swap Fuel Setup

    I don't think any of the factory LS configurations used a vacuum-connected fuel pressure regulator. Especially not any applications with a non-return fuel rail since the regulator would be well away from the engine, at or near the tank itself. But yes, 55psi is well within spec. A fuel leak at...

    Need help confirming a theory to fix an issue with the premium audio (7 speaker) system in my 2006 TJ Rubicon

    If the battery was at 9V with no load it's almost certainly smoked. It might come back from a charge but it's not long for this world either way.

    8.8 rear end seals (again)

    I know you said they're new shafts but... any chance they're bent? Or that the tube is bent, for that matter.

    Strange voltmeter behavior

    OP described it as a "dual USB that happens to have a voltmeter" - it's certainly just reading the actual voltage it sees at the 12V socket, it's not communicating with the PCM in any way.
