Hi, I have a ‘97 TJ Sahara with power steering and AC. I recently had my water pump replaced and a few days later my serpentine belt snapped. I bought a Continental Serpentine Belt from AutoZone (Part Number 4060910) and after spending over an hour was unable to get it around all the...

Hey y’all...did a quick search and didn’t see anything on this topic...I have an 06 LJ with the 6 speed. I’m having issues shifting into the even gears because the shifter is running into the tub cutout. It’s only recently become a problem. It seems like the driveline is out of alignment, but I...

Hi guys I got a 99 with a noisy rattling cat so i was looking to replace it. Before i order my parts i was looking into where it mounts to the manifold and that didnt look in too good of shape. so I started it up and stuck my hand up there before it got too hot and sure enough on one of the...

Hello everyone, I have a 99 tj with a 4.0 that was my daily driver for 2 years while at college until about 5 months ago I blew the head gasket and locked the engine up. Now that I’m graduated I want to get it back to driving. The fastest way would be to swap in another 4.0 I believe. Eventually...

Hello All, I have a 2003 TJ X with the 4.0 in it. Im looking at getting a new lower steering shaft as i have a ton of play in my steering and i believe this is my issue. Im running 33x12.5 tires, i can find the 97-99 steering shafts but having an issue with ones that fit a 03. Any ideas?

Hello, my Jeep sat for about 16 years with no attendance what so ever. Last week I bought a new battery, checked the spark plugs and the cabels. Spark plugs are recieving power so the problem is not the ignitionn system. I wanted to empty the tank but it was empty, I remember filling it up last...

Hello everyone, I just bought a 1999 Jeep Sahara about a month ago. I've been fixing up some general issues on it, one problem that I haven't gotten around to is the fuel pump replacement to fix its long start issue. I say that because now I'm having even more problems with starting. If I try to...

So I bought this Jeep a few months back with 213k miles and it ran good. Had a bit of a tick on start up then went away when warmed up, I’m told this is common with the 4.0 tj. However the ticking has gotten louder and when I give it gas the speed of the tick increases. Not sure if it’s lifter...

This boot on the shifter is torn and I need a replacement. Its not listed as part of the shifter and i have no clue what its called to look it up. Can anyone tell me what it is and its part number.

Hey y’all. I’m back at this place again. My $200 used catalytic converters have run their course. I’m losing the precat in bank 1. If anyone has a used one from a part out (particularly in CA) from a 2006 or similar TJ/LJ...I would be interested. I am really trying to avoid paying 900+ for a new...

So the lift kit, tires and wheels and SYE finally all got to my house and I had a free weekend to install it. Overall I’d say it was pretty straightforward. With the help of my two brothers and a car lift it took about 17 hours to install. I did a Rough Country 4 inch lift and 33x12.5 Pro Comp...

Hello fellow jeepers. So I have a weird issue. The ignition coil capacitor on my jeep is missing the hardware to ground it to the block. I have no idea how it happened, everything was mounted up properly a week or so ago. I went to check my oil yesterday and it was just dangling next to the...

Hi all, I have 1999 4.0 sport - has run perfectly for years, however recently it has developed a misfire when first driving the car. No issue starting the car but once I get off the drive and take it up the road it pops and bangs and judders until I floor it and it all seems to clear and then...

I was browsing the Jeep parts on facebook and stumbled across a turbo kit https://www.facebook.com/marketplace/item/492351671437786/

My TJ has 167K miles and I'd like to keep it through college, so the next 5 or 6 years. If I do regular maintenance, will it last? Based on what I've read, the 4.0L can last to 300K, but to be honest I think I'd feel better if I bought one with around 100K miles. Thoughts? Also - I know lots of...

Hey guys, I read the AX5 is only in the 2.5l. Guessing I have the AX15? What type of fluid do y'all recommend? Do you use any additives or conditioners? I bought this TJ a month ago and want to change the fluid. There's currently 170K on it and not sure of it's history. No issues with shifting...
