it makes a knocking sound when u turn the wheels.
Typical U-Joint noise. Makes noise in reverse but not in drive. Check both front and rear U-joints of the drive shaft. If one is bad replace both. You do not want to go through R&R of the drive shaft twice.
you remove drive shaft, exhaust, take the fuel tank down, change bad pump (you have 2) and then calibrate ECM since fuel pressure will differ...
Yes it will.
It won't.
If it is a rear wheel drive car you could have a bad U joint, bent drive shaft or a broken tooth or two on the ring and pinion gear. If it is a front wheel drive vehicle you may have a bent rear axle or bad bearing. If it is four wheel drive or all wheel drive you may have a bent drive shaft.
Sounds like you have a bad drive shaft.
Usually a bad U Joint - Universal joint connecting drive shaft to transmission & rear drive axle - there is a U joint at each end of the drive shaft - repair this ! Thew drive shaft can actually come off the car when driving - can be very dangerous.
NO. that's wat they are for to let it turn
it could be a bad universal joint.
I think you mean axle shaft joint. A crunching noise, especially when turning corners suggests bad axle shaft joints.
The shaft seal will leak or not work when the system has been properly bled.
