I have a 2000 chevy blazer 4x4 .I'm having problems with my right front wheel. when I go forward it almost sounds like I have a flat or I keep running over something. I have replaced the upper and lower ball joints the hub and bearings the brake callipper and rotor. what else could it be? this vehicle is important to me and my brother. our dad helped me get it. I made all the payments and it's payed off. our dad passed away a year ago and want to do everything to keep it running.

 

There is a gear in the axle on the passenger side that engages with the front differential when the 4wd system is engaged. Perhaps it is slipping and grinding???

Is the sound only when you are rolling forward? Does it happen when you 4wd? Can you replicate it when the front wheels are off the ground by rotating the wheel by hand?

 

I will try that tomorrow but yes it's only when going forward. thank you for your help I'll get back with you in a day or so and give an update. this vehicle is really important to me. ever since I got out of the army I wanted a blazer and my dad made that happen. thank you

 

no I can't replicate it when the wheels are off the ground and with me turning the tires
