Re: 2005 Yukon when I hit a bump there's a GRRRRR sound...
Almost sounds like maybe the ABS pump is engaging. Astro's were famous for doing that. if its the ABS engaging, its not exactly a problem. the vehicle is just detecting a wheel not moving at the same speed as the others for a split second. just a thought!

Get it to a reputable suspension shop to have it checked out,if it was said a part on the steering then you don't want to risk losing steering when the worn parts break.Speculating it could be tie rods,sway bar links,ball joints,bushings etc etc everything that moves when you hit the bumps.
Vibration from about 40-60 mph is usually attributed to wheel balancing, but the onset when you hit a bump seems to indicate play in the steering linkages (tie rods etc) or suspension members and stabiliser bar rubbers but you had that all checked out, that brings us back to the wheel balancing.
Hello. you have either a poor solder joint or a loose connection within the systems effected. The best route to go is this. look in the yellow pages under auto electric repair shops. have them put your yukon on their diagnostic equipment to pin point the problem. J.
It is common for the front sway bar links to wear out. This can cause a sense of looseness, with a slight rattle in the suspension when going over bumps, or when making turns. They cost about $60 a pair at auto supply stores, and can be changed in about 1 hour. There was also a GM technical service bullitin on this vehicle in regards to the steering column which is also a possibility, as well as one regarding loud knocking sounds related to the front strut spring cups.
hello dirt gets between the abs sensor and the MOUNTING SURFACE . in order to find which sensor it is .on the front abs sensor has to be unhooked wheels jacked up ,spin wheel clockwise by hand while check ac voltage .if the ac voltage is less than 200millamps this is the sensor that the surface needs to be cleaned,TURN WHEEL 3 TIMES AROUND PER SECOND! I HOPE THIS HELPS
