Humming Noise 96 XJ

[Bluewarrior7]

So I have this humming noise that becomes increasingly louder as I increase speed in my 96 XJ. I am led to assume it might be a wheel bearing, however I am unsure. Has anyone else encountered this problem and if so, how expensive or difficult of a job is this going to be to fix?

well humming noise could be alot of things, im not even going to try and throw out guesses but i can tell you how to check the wheel bearings and eliminate that. jack up the front end and grab the wheel and try to move it up and down. it shouldent have any play. if it moves up and down or side to side you wheel bearing is loose and is the likely source of the noise. you can buy the hole wheel bearing/hub assembly new at n e autoparts store between 25-45 bucks depending on weather or not you get OEM on Made in China haha. its not that hard to replace 3 bolts hold the hub to the knuckle and then like 1 1/4" for the axle into the hub.

If you can move it up and down it could also be your ball joints that are moving so make sure you check that the actual hub is moving. If it is moving side to side that could be play in the tie rod so check for that as well.

As for the price of a front unit bearing I would drop the money on a nice timken bearing which can be had at www.rockauto.com for a decent price but definitely not for 25-45 bucks. I have never seen a bearing that cheap. Also the axle nut is not a 1.25" nut but a 36mm nut.

amazon sells timken hubs for like 80 bucks

x2 on all of this.

you are not gonna find a unitbearing for 25 dollars, ever, if you do EVER..dont bother buying it, its prob made of paper mache

you can get a REAR axle bearing for that price, but thats an entirely different animal. and you aint installin that without a press.

guss i got the paper mache one, baught it 4months ago and its loose. was ony 30 bucks advanced auto parts, and thats about all i had at the time so i worked for me.

[HeavyMetal]

maybe they fucked the price, advance and autozone specifically are the ones who like to rape on the cost of those,m aka 100+.

never ever anywehre have i ever seen a unitbearing go for less than 75 new, and ive bought a bunch. lol

I may take you up on this once I determine if it's the bearing.
