might be the brake pad
My question is: What sound does a lion make ? Roar.
The tire itself may be bad, with a flat spot (no tread) or bulge. Also, a wheel that is badly out of balance can thump at some speeds.
It could be a break drum, rotor, or shoe. It could also be a bad tire. Sometimes they get a bulge, usually on the side you can't see.
Check for a broken shock.
You may have a rear tire out of balance.
It is more than likely that you need a new strut
Have those two front tires checked out there might be a bulge or a broken belt in the tire.
Its a slipped belt. Or even a bubble. My car did that only when i broke the stablizer.
Bad tire Bad wheel bearing Swap tires front to rear and see if problem changes Check wheel bearings for "play"
Bad tire? Rotate and see if thumping changes
It is not safe at all to do so.
A broken tire belt or bubble.
