knocking sound right wheel

hi

i have knocking in the right front wheel. it hapens most of the time around 40mph or also when driving taking a long smooth left turn. i suspected the fcabs and replaced them today. took the car for a spin and the steering definitely feels much tighter however the knocking is still there. could these be control arms (still orig at 98k). how can i check control arms if they need to be replaced ? is there anything else i can look for in order to fix this issue? it just feels like the wheel is bouncing around during those speeds or that turn. thanks

Wheel bearings, I bet...the right one. But, be careful assuming it's the front...probably is, but sounds can be deceiving.

Usually you'd replace rt. and left together, but it's possible you just took a hard hit on that side and thus it 'went out' a little.

If it's 'timed' to a wheel rotation, it's undoubtedly a bearing...front or rear. You might not be able to confirm so well by just spinning the wheels and listening with stethoscope, but you could try.

Also, if bearing, the sound will get worse and worse, and I'll just say you could probably drive for a month or more, but I'd get to it soon. In the front, the bearing is built into the hub. In the rear, you can replace just the bearing.

thanks for the nfo dmax! im pretty positive it's front right but ill double check. should these be replace in pairs too or if the other side is fine leave it alone ?

also this website has these already pressed into hubs so the DIY should be much simpler.

should i go with geniuine or MTC (the cheapest one) will do the job as well ?

upon some further inspection it seems like the driver front wheel spins freely where as pass side (the one with knocking sound) is almost as if it's seized, it takes a bit of muscle to just move it a bit. forget turning it with one hand. is this still the wheel bearing with hub issue ?

Read up on MTC...sounds like one of those brands that might not be so good...but who knows, could be OE. Search for MTC here and I'm sure you'll find feedback.

Typically you do things like this in pairs, but, as I said, one side might have been damaged by a hit, so one side is all you'd need.

Also, the front bearing is always pressed in the hub. The diy should be easier, but you'll need some special tools too. There was a recent thread about this...probably a number of them here.

Anyway, get into the wheel just to confirm things...it sounds like bearing, but you should check other basics, like make sure your wheel is on tight.

dmax it appears that the wheel in question is almost seized. i have to really get on it to turn it. it wont turn as easy as the driver side.

Based on your sound...I used to describe wheel bearing like a whoop whooping...that's bearing...I'm surprised it's tough to move, but you can confirm it's bearing when you remove caliper...

Have fun!
