Скачать или смотреть How To Break-In Fresh Gears & Lockers (Did They Survive 500 Miles?) | K5 Blazer on 40s

Gear oil change after 500 miles — the critical break-in service for new gears and lockers. In this video I drain the differential, show the metal shavings and what to look for in the used oil, and explain why this step matters if you want your gears to last.

I’m also upgrading to heavy-duty diff covers for extra strength and protection. If you’re running big tires, wheeling off-road, or pushing your truck hard, HD diff covers are a smart upgrade that keeps the housing rigid and the gears safe.

This service is being done on my K5 Blazer running 40s, but the process applies to most trucks, Jeeps, Toyotas, and 4x4 rigs with new ring and pinion gears or lockers. If you’re doing a differential break-in, here’s what to look for and why you can’t skip it.
