About Carl Brandt
Expertise Will discuss suspensions, lifts, lockers along with tire suggestions. Trail ratings and possible requirements needed for specific type of trails. Safety equipment and what you should carry with you. Certified off-road instructor.
I am not a mechanic, and 4-Wheeling is a hobby, so if I can't answer a technical question it is due to my mechanical knowledge being related to vehicles that I have owned, or have worked on. I do not have manuals on all vehicles.
Experience Experience in the area 40 plus years of 4 wheeling in a variety of vehicles. At the present time, my major off-road rig is a 94 Jeep Wrangler with a spring over and a 3 1/2" suspension lift. This gives me a total lift of 9" or so. I have lockers front and rear. I have removed the track bars, and sway bar for maximum articulation. I am running a stock 2.5 ltr 4 cylinder with a Jacobs ignition along with a K&N air filter. It has 4.56:1 gears with a Dodge NV4500 transmission along with a 3.8:1 Atlas II transfer case. This gives me a final ratio of 95:1 in low gear/low range.
Other vehicles I own, are a 95 Ford F-250 with a 6" lift, posi rear end, 35" MT's, 5 speed with a fuel injected 460 ci engine, and a stock 2000 Grand Cherokee.
Trails I have run are the Rubicon (10 times), Dusey Ershim, Fordyce Creek trail, McGrew trail, several trails in Moab, Utah along with local monthly runs.

Another way is to check the wheel bearings, they might be rusted or dirty, which might be the cause of the stiff turning. If so, try putting grease on them to get them slippery and easy to steer.

Hello, I own a 95 JGC. In the owners manual it states that the clutch on the cooling fan stays engaged as it is a heavy duty unit for towing. Mine has done the same thing since new. it does tend to be louder in the coldest winter months.
