The left front hub/bearing assembly was just replaced on our 2001 ford escape 4wd and it got rid of the loud grinding noise when you turned corners at hiway speed. now the issure is at all speeds, if you open the window at say 25mph you hear a really loud metal on metal rotating grinding sound, .... bad part? not installed correctly?
Anyone else that has this issue as a warning I had this issue on my wifes 01 Escape AWD V6 and it turned out to be the driveshaft center support bearing. Stealer wanted approx. $1000.00 CND plus labor to replace the complete driveshaft. They don't have to replace the complete unit, just send the driveshaft out to have the support bearing changed at a drive line shop. Cost to me sending the driveshaft out myself was approx. $200.00 CND.

Re: The left front hub/bearing assembly was just replaced...
The hub bearing is usually pressed in and can be pressed too much and damaged. Also,you may want to check to see if your brakes are worn out on the front which could also be making this noise.

Sounds like wheel bearing, an easy way to check it out is to just jack up that corner enough to get the weight off the wheel then with one hand on the top and one on the bottom of your tire check for any play. If there is play your bearing is bad. the play will most likely be very very little (less than 1/16 of an inch) but there should none whatsoever. if the grinding noise happens when turning left, check the right side or grinding when turning right check the left side. sometimes the bearing has a bad seal or wasn't properly lubed when being made.
If you still think the noise is coming from the left side CV joint it would be more advisable to replace the entire axle as an assembly. For the time and effort it takes, you can usually get a rebuilt axle assembly for only a few dollars more than the CV joint and the boot required to repair one. You will need a large axle nut socket (usually 30 - 32mm) to remove the axle nut. The lower ball joint and tie rod will need to be separated along with the brake caliper and rotor, from the spindle. I would recheck the grinding noise before doing it. A lot of wheel bearings are mistakenly diagnosed to the wrong side. If the noise is loudest when turning left, most people would assume the left side wheel bearing is at fault. However if the noise is loudest turning left it indicates the right side wheel bearing is most likely at fault. Due to the weight distribution of the front end, turning left the weight all transfers to the right side, loading that bearing. Make sure thats not the case before tackling an axle.
The bearings should be inside the drum assembly.The brakes do not have to come off. The bearings may have to be pressed out if they are sealed type bearings.
You also could have received a bad axle. Sometimes the rebuilds don't hold good tolerance and can make the same noise you are trying to get rid of. Is it full-time 4wd? Maybe the driveshaft ujoint also.
u have to take the hub off. and press the wheel bearing out. it takes alittle time to do bc u have to take your rotor and brake assembly off to get to the hub.
