Its hard to say... do u know where the noise is coming from?
it could be belt pulley rubbing on the timing belt cover or it could be the berries in the wheel but if its making grinding noise while ilding then def check your pulley make sure it isn't rubbing on anything or it could be the flywheel theres numbers of things to check over for the grinding noise
The rear of a Ford Explorer may have a grinding noise when driving, because the muffler may have came loose. The u joint may also be loose and cause a grinding noise.
The knocking noise could be one of several things. The wheel bearing, a worn steering or suspension part, or road debris could be causing the noise.
Perhaps worn brake linings? Bad wheel bearing?
countershaft bearing could be problem
Could be a bad strut or shock No I have disconnected both rear shocks and knocking noise is still there whilst driving. Seems to be coming from rear. When stationary I can bounce rear of car up and down and hear noise with handbrake on but not with handbrake off. Any ideas?
Dust build up on pads/shoes (squeal) Worn pads/shoes causing metal to metal contact (grinding) Suspension fault, movement of faulty component when the brakes are applied (knocking).
knocking noise
Wheel bearing
The knocking that you are describing reminds me of a stuck universal joint. A bent axle usually wears tires out very fast more than making noise.
I experienced a knocking noise in my 03 Xterra and found out is was a bad wheel bearing seal and had to have the Nissan dealership replace it for about $400 (includes labor and parts).
