Interesting. I may dig back into it. Lokkas are just fine up front, given manual hubs. I ran one for a while. I’ll ask Towndawg how his is holding up…I’ll see him in 5 minutes, lol.

These are known for exhaust leaks (at the manifolds and at the Y pipe), and lifter tick isn't uncommon, but I've never heard that pattern. Slow crescendo of ticks, then silence, then repeats. Not sure what to make of that. Might be a heat shield or a baffle in the muffler that's loose. I don't know what would make an engine noise come and go like that. I am of course assuming that's actually what's going on and the potato the seller filmed with doesn't have some kind of background noise cancelling that's playing silly buggers. The acceleration video sounds like it's got a hell of an exhaust leak, or no muffler, though again I don't know how much is the truck and how much is the mic in the guy's phone.

Sounds like the normal manifold leak. What is the actual cause of the problem? Most likely manifold studs breaking. Is it fixable? Absolutely

Yeah, I’m long with words sometimes. No LSD options for the front, so nothing to repack.

One of my favorite topics. I'll take a different path to promote further discussion, but for starters I'll say an LSD (even a repacked one) isn't a true substitute for a locker. They're great for having a street and trail balance, and they can be made to do very well off-road, but they're simply not a locking differential. If there was a traction level chart that was specific to our trucks based on available device options, it might look something like this: Level - Front Diff, Rear Diff, Suitable Trail Use (Green/Blue/Red) 0 - Open, Open, Green 1 - Open, LSD, Green 2A - Open, Mechanical, Green/Blue 2B - Open, Selectable, Green/Blue 3A - Mechanical, Open, Blue 3B - Selectable, Open, Blue 4A - Mechanical, LSD, Blue/Red 4B - Selectable, LSD, Blue/Red 5A - Mechanical, Mechanical, Red 5B - Selectable, Selectable, Red Clarification points: For LSDs, there's obviously a scale between OE-spec LSD units and re-packed units, but they're still in the same traction level. "Mechanical" refers to auto-lockers (auto-unlockers, lunchbox, etc.) like Lokka (front) and Blokka (rear) units. "Selectable" refers to any locker that can be disengaged on demand, regardless of actuation (air, electric) : ARB, TJM, TRE Selectable lockers always have the advantage over a mechanical locker because they can be disengaged. This is particularly important when in tight steering situations, and everyday street driving. (This discussion ignores the use of manual hubs.) Levels 0 & 1 are still fully trail-capable, provided all tires stay on the ground. Once one tire lifts off the ground, especially on an incline, limitations immediately kick in. Notably, it's relatively easy to lift a tire with IFS. When coming from Levels 0 or 1, I advocate locking the front diff (level 3) before locking the rear (level 2), mainly because of issues that can occur when a front tire is off the ground and not rotating in unison with the other tire. That is, if you have a front tire spinning off the ground and you land on it, it's bad on the CV, mmmmkay? I'd skip level 2 for the most part. Level 4 & 5 do great for wheeling, provided you're mindful that an LSD is not a locker and that, at some point, it will start to act like an open diff. Red usage would basically warrant a re-packed LSD.

Limited slip differentials are a more affordable way to get better rear end traction on most surfaces and in most driving conditions. However, in extreme cases such as rock-crawling or climbing very uneven and steep obstacles which could result in a rear tire having little to no traction, a locking differential provides the best solution in order to overcome the obstacle with the least potential for damage. Damage could be caused either by excessive wheel speed which could result in drivetrain damage, or excessive vehicle speed, which could result in loss of control, leading to undercarriage damage, body damage, and/or drivetrain damage. A very tight LSD could potentially cause some handling/cornering issues on pavement. If you do little to no rock-crawling, the LSD could be a satisfactory option. In my case, the effort/expense of pulling the third member, repacking the clutch pack to increase the breakaway torque, then reassembling it, was not worth the risk of discovering that it still might still not provide enough performance benefit for my style of 4-wheeling. It is for this reason that I opted to just go all-in with an ARB air locker. My R50 is air-lockable both rear and front, but it took a decade of wheeling for me to get to that point. Every driver's situation is different, so the approach to mods I would recommend is to run the trails you enjoy, get lots of seat time to learn how to drive within the vehicle capabilities, learn to choose good lines, and plan your vehicle upgrade path accordingly. Tires are probably one of the most important things to start with, with a lift being next. I would prioritize recovery equipment above drivetrain mods. A locking diff or tight LSD may only give you the ability to get you stuck further down the trail.
