Tie rod - Toe-in Allignment

Improper toe settings may cause your vehicle to handle strangely and wear out its tires rapidly.
Only 1/8 inch of toe misalignment front or rear produces the equivalent wear of scrubbing the tires sideways 28 feet for every mile traveled.

Excessive toe-in causes tire wear on the outside of the tire and can also make the car oversteer and dart back and forth across the road. Excessive toe-out causes wear on the inside edge of the tire

Remember, worn outer tie rod ends are a major cause of abnormal tire wear, as toe cannot be accurately set when these components are worn. So replace tie rod ends of there is play.

Changing Differential Fluid

Owners manual says to refill F&R axle every 12K miles under heavy use (off-road, towing, ...), but doesn't give an interval for normal use.

At GetAHelmet.com/jeeps/ they say:
I try to change my diff fluid in my rear axle at least every 15,000 miles and around 30,000 on the front axle since it is only under load during the occasional 4x4 trip.

Faulty turn signal flasher unit
My turn signals will only flash a few times on 2001 TJ then stop.
Dealer wants to sell me the whole unit with levers, $125.
The flasher module (Part #04607084AB 50732 2(4) x 32CP - 12V) plugs into the switch assembly but is hard to find.
Where to get repacement flasher (not LED) - JeepForum.com says,
Try a junk (salvage) yard
or GCD Offroad - An Ultra Care Car Products, Inc Company Jeep TJ after market Flasher LED 2001-2006 $29

On some of the types of "LED replacement" flashers the middle pin is wired up incorrectly for the Wrangler so that when you press the hazzard button you get a short circuit and your 20A fuse blows.


Remove rear wiper arm to replace motor.
It's a hassle, but the right way to use penetrating oil is to apply it and tap the bolt. Then re-apply and re-tap the bolt every so often. The tapping (and this is a slight tap) is to help break open some cracks to allow the oil to penetrate further. Having a gear/bearing puller on there helps increase those cracks for the oil. Applying heat can help the process but you want to be careful not to cause damage to the surrounding materials (ie, the paint). Bear in mind that if you heat it you'll likely evaporate the penetrating oil, so be sure to reapply it.

A few months ago someone decided to snap my rear windshield wiper arm in half for fun so I had to replace it. I tried using a puller, pliers, and brute force and it didn't work. I ended up having to use a dremel to cut through it to get it off. Just be sure not to damage the bolt.

Try a caulk gun. Apply the slotten end under the wiper arm around the shaft and apply pressure on the backed-off nut by pressing the trigger extending the plunger. Works better then the gear puller.
