Trail Safe Inner Axle Seals Pair For 79-95 Pickup 85-95 4Runner Trail Gear

Inner Axle Seal. Seal is 100.0 Percent rubber coated. Seal lip is supported by a garter spring applying constant force to the full circumference. Outer seal lip acts as a secondary seal. Keeps debris and other contaminants away from the inner seal lip. Figure A:Deflection gaps in the Brand X seal are the result of the spring clip opening. Fluid is allowed to bypass the seal lip through these deflection gaps. The result is a leak.Figure B:The Trail Safe seal lip is totally supported by a garter spring. The spring applies constant force over 360.0 Degree, not allowing any deflection gaps. This means no fluid leaks.Figure C:The spring clip opens up under deflection and no longer supports the seal lip. A deflection gap will allow fluid to bypass the seal, resulting in a leak.Figure D:The Trail Safe Inner Axle Seal uses a garter spring which offers 360.0 Degree of support around the seal lip during deflection. This stops fluid from bypassing the seal lip. No leaks.Figure E:Brand X's attempt
