Just picked a 97 4dr with 153k miles on it. I can hear a faint scraping noise from the front left wheel. It seems to speed up or slow down with the speed of the wheel. I'm assuming that this is a wheel bearing/hub issue. How big of a deal is this to replace? Additionally, I have a oil pressure gauge that reads zero constantly although I seem to be getting actual pressure as the motor runs smooth. Sensor? Sending unit? The last problem that I've found is that the blinker refuses to cut off after the wheel is straightened back out. Not a hug deal but it's slightly annoying. Any thoughts would be great.
well with the blinker its jsut a little catch and its inside the steerin column, i've yet to dig into that yet though. but the wheel bearring is vairly simple i jsut replaced mine. ya put in up on jacks tae the tire off, remove the brake caliper with what should be 2 torque nuts in back, after that it is 3 bolts on the side twords the engine there are 3 bolts to losten and it should come i believe if i remember right, also its a good time to see if ya need new u joints sinse its already off.
well Ive done the hubs a few times in the past month now. First your going to want to pb blast the hub bolts, and once you get those out, the hub will probably not come out, so the way i did it since i was already replacing hubs and didn't care for them, was to bang on them with a 3 or 5lb sledge. This will eventually get the hubs out, just takes a few good blows. If that doesn't work try a pickle fork, but it will defiantly mess up the backing plate. Also I know there's a way to take of the hub using a 13mm deep socket, but i haven't tried yet. Just search that option. So pretty much it will take you probably an hour or two, depending on how much stuff is rusted in there, Its not that bad though.
Good Luck and have fun
Raise the jeep up and place on jack stands. Place one hand on your coil spring and spin the wheel with you free hand. You should be able to feel in the spring if you have a bad wheel hub.
This is how I was told to look for a front wheel bearing issue...
My mechanic said that they put it on a lift all 4 wheels off of the ground. Put it in 4WD High and when up on the lift, start it and have a friend put it in gear. Under very slight acceleration (a friend doing this obviously) you do the spring test. The one with the vibration is the bad one. Too bad that they are not serviceable units... but they are still easily fixed.
Also, sounds like it could be a bad caliper? Pistons not releasing properly?
so you replaced the hub/bearing carrier as a unit...both sides? replaced with tappered bearings included I assume? What was the cost for each side? Anything else to order to get it done?
You can't replace the bearing itself, you have to replace the entire hub. They are non-seviceable units. Be sure to get the good ones or they won't last long.

yeah, I lowered my front end when I did my lift an now my dust shield rubs really bad. I wedged something in between the rotor and the shield...hopefully it moves back out as it is just sitting there...bunnyhunter is right, check that first, especially if its been lifted or worked on by the PO
