As many of us with the 3 speed auto transmissions know, bigger tires and lower axle gear ratios provide great power, but really run freeway RPMs up. Anyone have a thought on max RPM to cruise at on the highway for a couple hours or more? With 33s and 410s, I’m tacking over 3000 rpm at 70. In...

Sorry for what seems like a silly question, but I am unsure. When an aftermarket locker says for 3.73 and up. Does the ”up” mean higher number gear ratio, 4.10 as an example, or an actual higher gear ratio, 3.03 as an example? Jeff

I’m sorry to post this, but all the threads I have found provide links to pages and charts that are gone! The few I have found do not agree. I have a 1999, TJ with 4.0, auto and 4.11 gears. I went back to 33s from 35s. Well they are almost 33, they are wildpeak, 285/70/17 tires which I think...

I usually post on my 1999 TJ project. But I am helping my son on his 2001 TJ. He has gotten a PO303 code now that trips the CEL. He has changed out, the fuel rail, spark plugs, added Cool packs, foil insulation kit around the fuel injectors and the OEM Insulator kit. He is still getting the...

I am running aftermarket JK wheels. Tires are shot so I bought a new take off set of wheels and tires from JL Rubicon. Put the on the spacers and the wheels fit pretty good. Put a lug nut on and it seemed small and didnt seem to fill the ”cone“ up in the wheel right. I called the guy I...

I have a 1999 in Arizona. I have recently flushed the radiator and replaced the coolant. I have recently upgraded to 4:10s & 35inch tires with a 4.0 and automatic. Some questions on temp and thermostat. Right now it runs around 190 running to the store and such. Out on the highway running...

I believe I have a RMS leak because there is a leak in that area. But I also worry it is not a RMS as I have power washed the bottom of the engine and tried to clean all the pan. When I drive for 10 or 15 miles now and pull back in the garage I have an “oil burning” smell for a good couple of...

Guys, I just finished installing my SYE on my 1999 TJ. The only thing that seemed less than great was the slip joint in the driveshaft seemed tight and stiff. Definitely couldn't push it shorter or longer without a rubber mallet. But then U-Joints are tremendously stiff and tight to begin...

After replacing all my control arms, Steering, both front and rear axles and gears, steering gear box and numerous other improvements, maintenance and upgrades to my TJ, I thought I was no longer a Newbie!! But every day under the jeep humbles me more. I just installed a SYE in the transfer...

Below is a pic of my Dana 35 rear end and custom cover, (not sure what brand or who put it on, some PO). I believe the top hole is the fill hole. I believe the lower Allen bolt is the "full" or inspection hole. However when I take that bolt out, lub comes out like crazy. I worry that means it...

Sorry for the long post guys. If you can get through it and comment, all comments will be appreciated. Even if you think I have been stupid, (probably have). I have a 99, 4.0 automatic with 35 MTRs. It also has a 1 1/2 inch body lift. Done before me. I recently put new axles with 4.10/11...

I have seen this question before but with conflicting answers. I’ll try again.. I installed, (just about done), new front axle with 4.10/11 gears. Due to the virus complications my rear axle is not going to be done for at least a couple weeks. My question is simple. I have a 1999 TJ with...

I hope I am posting correctly here. Since I have started this forum I am amazed at all the cool jeeps, but more amazed at what you can learn and how informative and helpful everyone is. Since the last time I owned a Jeep, (before Jan 2019), was a CJ5 in 1988, I don't feel like I can contribute...

I have a 99, 4.0 TJ with 120,000 on it. Past owner is gone and I have almost no past info. Coolant overflow bottle was clogged with red/orange gunk and totally discolored that color. Radiator was gunked up some, but not terrible. I drainer the radiator and the coolant was red/orange after I...

Does anyone have a good TJ jeep shop to recommend in the Phoenix area? Preferably in the East Valley? I have oil & PS leaks front and rear, appears to be Gearbox, steering shaft seal and possibly PS unit itself and the rear main seal. Can't see any oil from above. I just got back into Jeeps...
