Loud Roar At Highway Speeds

mthackerson · **Posted:** Fri Dec 14, 2012 12:28 am

CRD has a loud roar at highway speeds, thought it was the tires they have about 2/3 wear, but had them rotated and it didn't get any better. The roar doesn't increase on acceleration, just is consistently loud at highway speeds. Any thoughts? I'm at 140,000 miles

Front wheel bearings? Although if they rotated your tires and didn't notice it, I have to wonder about the tire shop...

if the tire wear is matched, rotating won't change it much, if at all.

for a test try increasing pressure about 5-10 psi (for a short distance)
just to see if the sound changes.
If it's tires - the noise will be different
if it's bearings - it'll sound the same.

I'm trying to decide what wheel hub unit bearings to go with on my Liberty. Rock Auto has several options.

Raybestos Professional Grade - 102 per side
Timken - 141/144 each
Moog - 155 per side
SKF - 203 per side

Any input on the different options? So far as I see, they're all 12 month warranty. Is there another recommended brand/source to go with?

Also while doing this is there anything else that you should do? Brake pads since they calipers are off, etc?

Timkin

That was my first thought too, but wasn't sure if there was any reason to go with the Moog. Are all Timken products still USA?

I need a new right front wheel bearing as well and experience alittle bit of roar when driving. I would go with the timkin They're only about $140 or somting in that range on amazon. Just search the part number from the parts store website.

as opposed to the autozone price

you can look around. Amazon has some good prices on parts and Ive had good experiences using them.

A good portion of them are if they ALL are not. I would trust them over most other brands. There are several large Timkin manufacturing operations in Ohio one about 15 min away from where I live.
