1998 isuzu rodeo: 4x4..the wheel or axle because it speeds up..tire

This answer was rated:

1998 isuzu rodeo 4x4 There is a whirring or roaring noise that seems to originate close to the right front wheel. It is connected to the wheel or axle because it speeds up or slows down with the vehicle's speed. Like a rock in the tire type of sound but no click.



A roaring noise is typical of a bad wheel bearing. Jack front end up and check for play in wheel when trying to shake tire. If there is, replace wheel bearing assembly:


  • Place the transfer case in 2WD.
  • Raise and support the front end.
  • Remove the caliper from the anchor plate and suspend it out of the way.
  • Remove the rotor.
  • Loosen the caulking around the front driveshaft nuts. Remove the nuts and discard them.
  • Remove the 4 hub retaining bolts.
    NOTE If the hub is difficult to remove, install 2 long bolt in the bolt holes and strike them to loosen the hub.
  • Installation is the reverse of removal. Torque the hub bolts to 76 ft. lbs. (103 Nm). Use new driveshaft nuts, torquing them to 181 ft. lbs. (245 Nm). Apply new caulking. The caulk should be free of cracks when applied.
