* Ball Joints: These are crucial components connecting the steering knuckle to the control arm. A worn ball joint will create play, and the clunk is likely the sound of metal-on-metal contact as the suspension moves under stress (turning and hitting a bump). The right turn emphasizes the right-side ball joints.
* Tie Rod Ends: These connect the steering linkage to the steering knuckle. Similar to ball joints, worn tie rod ends will have play, resulting in a clunking sound when the suspension moves. Again, right turns put stress on the right-side tie rod end.
* Control Arm Bushings: These bushings are rubber components that cushion the control arms. Worn bushings allow excessive movement in the control arms, resulting in clunking. The combination of turning (side load) and hitting a bump (vertical load) is a particularly harsh test for these bushings.
* Sway Bar Bushings/Links: The sway bar helps control body roll. Worn bushings or links can lead to clunking, especially when turning and hitting bumps, as the sway bar is actively working to stabilize the vehicle.
* Steering Gearbox (less likely but possible): While less likely to produce a simple clunk, a failing steering gearbox *could* contribute, especially if there's excessive play in the steering.
Troubleshooting Steps:
1. Visual Inspection: Carefully inspect the front suspension components for any obvious signs of damage, wear, or loose parts. Look closely at the ball joints, tie rod ends, control arm bushings, sway bar links, and sway bar bushings. Look for cracks, excessive play (try grabbing components and moving them), or signs of leaking grease.
2. Suspension Test (with a helper): Have a helper gently rock the vehicle from side to side. Pay attention to any play or clunking sounds. Then, have the helper push and pull on each tire while you listen for unusual noises. Focus your attention on the right front wheel.
3. Professional Inspection: The best approach is to take your Blazer to a qualified mechanic for a proper diagnosis. They have the experience and tools to pinpoint the problem accurately. A simple visual inspection might not be enough.
Safety Note: Driving with a damaged suspension component can be dangerous. Do not delay addressing this issue. The longer you wait, the greater the risk of a more serious accident.
