Product Overview
Clunking through the steering column, a loose spot at the wheel, binding, or rusted universal joints can point to worn steering shafts. This set replaces both the intermediate and lower sections so the connection from column to steering gear can be serviced together.
Steering is safety-critical. Confirm the noise is not from tie rods, rack, column, suspension, or body mounts, and keep the wheel and gear centered during replacement.

Frequently Asked Questions
Q: Can these shafts cause a steering clunk? A: Yes, worn slip joints or universal joints are common sources, but the rest of the steering and suspension must be checked.
Q: Why must the wheel stay centered? A: Rotation with the shaft disconnected can damage the clock spring and misalign the system.
Q: Does the set fit an H2? A: No. It is listed for H3 and H3T applications only.
Q: Is an alignment required? A: Shaft replacement may not change wheel alignment, but steering centering and a safety inspection are necessary.
