Question Wheel bearing hub assembly replacement

My Baja has been making a thumping noise similar to a flat tire from the front left wheel area, and it seems to getting a little louder. I don't hear any metallic scraping types of sound unless I turn right. It happens when I go straight or turn right. Not so much, if at all, when I turn left. The thumping speeds up, or slows down in relation to my speed. I'm assuming this is my wheel bearing going out.
Watching various youtube videos, it looks like it isn't too difficult, but I always seem to run into that one piece that is impossible to get at, or remove. I would rather just replace the whole hub assembly because I don't have the proper tools to replace just the bearing. How difficult is it really? Is there any part of the job that I might run into that will be difficult? What tools should I have to do it? I guess I could just take it to the shop if it'll end up being more of a hassle.

According to your descriptions it doesnt sound like a bad wheel hub. Normally your hubs start to hum at increasing speeds and it takes a good ear to pinpoint wihout lifting your tires. In my opinion, i think it could be your driveshaft or your center bearing. Or could be a driveaxle but i doubt it.
I have changed wheel bearings and three driveshafts and according to my personal experiences, i think you have a bad driveshaft but it is difficult to suggest without test driving it myself. Maybe somene has another opinion but i strongly suggest taking your car to a mechanic if you are too savvy with cars.

Sounds like a good idea. I would hate to replace something only to find out that wasn't the problem.

One more thing if your trannny is automatic you need to do research on noises u describe because Maybe its a internal problem. I hope something is just loose or a driveaxle but I have read about something with automatics. Maybe someone with a automatic can greater inform about the pros and cons of an auto

Mine is a 5 speed. I had a friend drive it while I ran along side of it to see exactly where the noise was coming from. It's definitely coming from the hub area. The squeaking noise sounds like a cross between bad bearings, and a noisy spring mattress. It's not a constant sound, but a squeak, squeak, squeak...in relation to the speed of the vehicle. From inside the car, it sounds like the thud from a flat tire.

Since you have pinpointed its coning from the front end, then it is a good idea to lift the car and see if anything is looose like ball joint or tie rods. To my best an honest opinion, hubs do not make thumping noise or squeeky noise. Hubs humm until it is obvious what wheel it is coming from. That squeeky noise that you are hearing is the the driveshaft that its close to the tranny. The yolk is binding and everytime you are taking off and fades away. You need to lift the car and inspect the front end of the driveshaft and see if there is any play.
I wish i can personally ride your car to really pinpoint the source but i am only going by hunch. If i'm wrong, then i atleast tried to help.

You need to check that soon because if it is the driveshaft. It can break any moment you hit the gas at a light.

I am having a very similar issue with an 08 Forester. My passenger rear is thumping.. I saw this thread last week and took my car over to a friend of mine with a lift this evening so I could look underneath. The shafts in the rear do not move, there is no sign of damage to the boots and since I can't replicate the noise with no load on the tires... I am at a loss.

Same symptoms.. under load when I turn to the left it gets a little louder than going straight and when I turn to the right, it goes way down in volume along with the thump that I feel through the car. I don't hear it until I hit about 20.. I am very sure it comes from that corner.. the car rattles so much that any vibration makes it rattle even more..lol. That corner really rattles!

I could just replace the hubs and the shaft on that side an hope a scorched earth approach takes care of it..lol. I am going to switch the tires just to be sure it isn't wheel/tire related.

You think its the shafts?

I won't have time to get underneath there to look at it a little closer until Saturday. From what I can see, the CV boots look fine. The noise is getting a little louder, and it'll do it now when I'm turning left too. The squeak is louder now too. It won't do it when the wheel is under load, but once I let it coast, the noise comes right back. In reverse, you can still hear it, but it's barely audible. I can feel it a little bit through the steering wheel, but not anywhere else in the car.
I hung out the right side of the car while someone else was driving to see if the sound was just as loud on that side, but it certainly does not sound like it's coming from the middle of the underside at all. Hopefully it's not the driveshaft, I priced out the part and it is spendy.
Hopefully it'll last until Monday when I can get my car in the shop if I have to take it there.

Talking Update

I finally got around to getting under my car, and taking things apart. It's definitely the front left wheel bearing. The drive shaft seemed fine, no play. Thank goodness, that would be have been an expensive fix. I took out the axle shaft and inspected it. It looked fine, and no excessive play. When I spun the hub, there was definitely resistance, and a scraping sound.
I don't have the proper tools to replace it so I'm just going to have the pros fix it. Even though they are sealed bearings, it's definitely not so sealed now. I pressed in some grease so now it doesn't make any noise. I wasn't sure if that would help, but obviously some of the grease got in.
I know, it's a band-aid measure, but it'll have to do until I get it in the shop on Monday.
On another note, it's probably not a good idea to use a air ratchet on the control arm bolt. I ended up stripping it by using one to remove it.
All that just to find out that it was a bad bearing. Oh well, I needed to replace all of the lug studs on that hub anyway.

I am glad that it's only your wheel hub. I replaced my bearing and it is not that easy especially the ball joint. It's hard to suggest problems over the computer but I'm happy it's a cheap fix.
