you don't want OTK unless your lift height is 6"+ IMO. You'll also need to raise the mount for the trackbar (axle side)

So if I was planning 6.5 lift OTK would be better? Trying to plan things out so I don't have to buy doubles of things now while I fix things and save up for the lift.

After 5 or 10 minutes of driving and praying the car doesn't die, the voltmeter jumps up to normal and everything is fine. It's just started doing this since the temps are getting colder, almost like the alternator has to "warm-up". I checked and the alt is spinning so I know it's not a belt slipping issue or anything like that. Thanks for any help!

girlfriend was driving our 95 jeep grand cherokee 4.0 and it just suddenly died as if the key was turned off. After dying it would crank but not start . had the jeep towed 120 miles home.
Replaced: coil, wires, plugs, crank sensor, ASD relay, timing chain (was time anyhow).
DTC codes: 43 Spark/ignition control circuit problem
42 Automatic shutdown (ASD) relay circuit problem
47 Battery voltage sensing circuit problem (volts too low)
21 Oxygen sensor (this has been disconnected for over a year)
when I try to clear codes with innova 3120 CanOBD 2&1 diagnostic tool it just thinks forever without clearing codes, yes Im sure im doing it right. Disconnecting battery did not clear codes either which really confuses me.
I am at a total loss, no fuel or spark, which I assume is a result of the auto shutdown. Tried jumping terminals 87 and 30 of ASD relay and still no start. Tried jumping terminals 87 and 30 of fuel pump relay and cant hear the fuel pump run. Wondering if there is a shut off switch somewhere that needs to be reset (like after an accident) or if this vehicle even has one. Its somewhat unclear based on what I've read so far. Current thoughts are either the fuel pump, fuel filter, or the brain. I have put a lot of money into this already and dont want to just keep replacing stuff untill it works (which is what I normally do) any help would be greatly appreciated.

So I'm starting to lose faith in myself with a tool in hand. Am I just looking over something or should I never touch a ratchet again? I'm replacing my fuel tank and am for some reason struggling to get the lock ring off the old tank! I have my punch and hammer but this thing is not budging. I don't want to hit to hard and damage it but it is bending some of the tabs before it is moving. There are two tabs near the lock ring that look like they could be locks or something? Any advice? I have it soaking right meow in some penetrating oil. Should I just go buy the removal tool and pray it works?

The pump is going on a new tank, any tips on how maybe I can clean it out? there is quite a bit of sediment on the inside of the tank and on the filter of the pump. Any help appreciated.

I want to do a proper flush on my cooling system, since the coolant in my overflow tank looks nasty, and i have no idea when this system was last flushed. I was going to use Prestone's Flush N Fill kit, but the instructions look like they were written by a 5 year old.
So i decided **** them, and I'm just gonna do a chemical flush. Any recommendations on brands? And how much would a non-Renix system hold?
