3.7 engine reputation
the 3.7 has a reputation of dropping exhaust valves due to a poorly designed valve retainer that doesn't allow the valve to rotate during combustion and then it overheats. PO of my '02 KJ had this happen, it's a common failure point (google is your friend) but I assume at some point they changed...- mercdudecbr600

Lockers or not
I put an early lunchbox locker in the late 90s on my old ford 60s muscle car and it grenaded (stopped working) after a few years of driving. I imagine things have improved since that time period but it put a bad taste in my mouth on lunchbox lockers. By comparison, LSD are much smoother and much...- mercdudecbr600

Lockers or not
Arb requires a compressor and air lines, which means extra money and can be damaged or leak. Ox locker uses a heavy cable that can be actuated by electric shifter.- mercdudecbr600

2006 Liberty 4x4 with 3.7L - Scheduled Maintenance Is Critical
Well I've been running NGK iridiums for the last few years. No issues, good mileage, power, idle, with very little wear on the plugs. I guess YMMV- mercdudecbr600

Noob question- alloy vs. steel
Got an OEM 16" KJ steel wheel in hand: with hubcap weight is 26.5lbs, net offset (measured to edge of rim subtracted by the wheel lip diameter) is 5 1/4". Otherwise, the total offset is 5 3/4" My OEM 16" KJ Alloy wheels measure 5 3/4" total offset (or 5 1/4" net offset), and weigh at 21lbs. So...- mercdudecbr600

Napa or Mopar reman
Napa lifetime axles have the warranty, which is probably what makes them the best for lifted jeeps. When/if they get damaged just get them replaced. Fairly inexpensive too- mercdudecbr600

Rear control arm help!!
I had a mevotech supreme installed for 2 years, which I ended up replacing. The ball joint was fine and still tight, it was one bushing that tore, most likely an install issue on my end though. But lifetime part, so I got a new one for free. 6 months later no issues- mercdudecbr600

Lockers or not
You can also look at the axle tube near the shock mount and there should be a tag that says “trac-lok”. Mine came with one and it’s decent for street use. Can get scary in snow/ice like any lsd. I had my tracolok carrier rebuilt and it’s sitting in my garage, let me know if you want it. That...- mercdudecbr600

2003 Liberty Lift Help - Any Advice?
So what I was thinking was clevis lift and top plate lift. Which has been said on this forum multiple times that it doubles the lift of the spacer. But honestly I don’t understand how a top plate spacer lift is any different than what the op is doing considering the spacer sits on top of the...- mercdudecbr600

You don’t get any extra vibration from the driveshaft without the counter weights? And what about the sway bar - on road handling must be affected, right?- mercdudecbr600

Noob question- alloy vs. steel
I believe it’s the 3rd gen explorers that use 16” steel wheels and those have smaller bore. now that I think about it, smaller bore on the wheels = incompatible with our Jeep- mercdudecbr600

2003 Liberty Lift Help - Any Advice?
I think, if I’m not mistaken, the spacers at the top actually double the height you achieve. So 2.5 spacer = 5” lift. That might be your issue. I know there’s a thread on here that talks about installing a small 1/2” spacer up front and how that will give you about 1”. Which is what I did on my...- mercdudecbr600
