QU40402 Dana 60/70 Flanged Pinion Seal

QU40402 Dana 60/70 Flanged Pinion Seal fits most mid-2000 and newer Dana-Spicer Model 60 and Model 70 axles. This genuine original equipment seal fits late production housings with deep seal bores. This seal can be identified by 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 QU40397 V-Seal.

Applications

Tech Note 1: 2nd Design Change in 2000
Dodge and Ford first used this seal in 2000. For 2000 and 2001 you may find a different, non-interchangeable seal. QU40097 may be found on some 2000 Dodge Rear Axles and QU40348 may be found in some Dodge and Ford front axles. QU40402 was phased starting in mid 2000 model year axles to replace the earlier seals. QU40402 and QU40348 are NOT interchangeable as the axle housings are bored differently for the two seals.

Tech Note 2: When Installing
Great care must be taken when installing this seal to insure that the face and body are not distorted.

Tech Note 3: Seal Failures
A grooved pinion yoke will usually cause a new Pinion Seal to fail after a short time. 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 by 0.020"-0.040". When a stock seal, engineered for the original yoke 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. Usually, the only long-term solution is to replace the yoke. Other common causes of seal failure are installation errors, not lubricating the seal lip and yoke with clean grease, and object damage such as getting grass wrapped around the Pinion Yoke.
