QU40335 Thin Dana 80 Pinion Seal for 2000-2001 Ram 2500, Ram 3500

QU40335 2000-2001 Ram 2500, Ram 3500 Dana 80 Shallow Shell Pinion Seal for 2000-2001 Dodge Ram 2500 and Ram 3500. This seal fits early production housings with shallow seal bores. This seal can be identified in the vehicle by the absence of an external flange that seats against the front face of the axle housing. A band of sealant is factory installed to seal against leaks between the seal and housing. This seal is used in conjunction with QU40251 V-Seal.

Applications

Tech Note 1: Pinion Seals
Most 2000, some 2001 and possibly a few 2002 Dodge Ram Dana 80 rear axles use this shallow shell seal that seats against a step in the housing bore when fully installed. Later production Dodge Dana 80 rear axles use a deep shell pinion seal (QU40248) with a metal flange that limits seal installation depth. The two seal types are NOT interchangeable.

Tech Note 2: Wear
Oil seal leaks can be very vexing with rear axle applications. The most common cause is simply the axle vent system is plugged. When this happens, pressure builds up as the axle warms up during operation until the weakest seal fails. The cure is easy, clean the vent hose and/or fittings (usually found on the left axle tube). Another common cause is a seal wears a groove in the pinion yoke. In these cases, replacing the yoke is the way to go. Installing stainless steel wear sleeves marketed by most major seal manufacturers would seem like a viable alternative, unfortunately, this type of repair rarely lasts long. Why? A worn sleeve increases the diameter of the yoke or spindle by 0.020"-0.040". When a stock seal, engineered for the original yoke or spindle diameter is installed over a wear sleeve, the larger installed diameter of the sleeve causes the seal to run hotter and wear much faster than normal. Result: Rapid seal wear and presto! the oil leak is back.
