Expert Installation Tips
Based on our manufacturing experience and feedback from repair shops, here are professional tips for basic maintenance and installation.
Use Proper Tools: We strongly advise using a professional bushing driver and matching reamer. Never hit the bushing hard, or it will bend.
Proper Grease Injection: After installing, you must pump in high-quality extreme pressure grease until it comes out evenly from the edges. This ensures perfect early lubrication.
Check the Gap: When finished, use a dial indicator to check the gaps on the steering knuckle and axle. Make sure they match the original OE specs.
