Review on LUBE LOCKER LLR-D030 Lubelocker: Superior Sealing Solution for Optimal Lubrication by Reginald Holman

This is what you need when doing diff maintenance. No more fumbling and prying to remove caps or scraping and scraping silicone when it's time to change the fluid. I paired a LubeLockers Dana 35 and 30 with Dana gray hammer head cast iron diff caps to complete the axle service. I tightened the caps to 20 pounds per foot, which is plenty on these 1998 and 2000 Jeep TJ seals.
