when i drive down the highway at normal highway speed, i get a rythmic groan. i cannot tell if it is speed sensitive but I suspect it is.

i think the only way to test wheel bearings is with a load and maybe a microphone close to the front wheels which is impossible for me.

so is the only way to see is to remove them and visually inspect the rollers?

they are fairly inexpensive parts anyway so I might just change them out. I just need help in the diagnosis.

groan....nothing.....groan...nothing...groan......ugh
