Applications

Tech Note 1: Driveshaft Slip Stubs
For driveshaft slip stubs, QU40618 Seal fits the unsplined portion of splined stubs measuring approximately 1.15" to 1.16". The spline Outside Diameter will be 1-3/8". The spline count can be 15 based on 16, 16, 31 based on 32, or 32.

Tech Note 2: Spicer Type Driveshafts
QU40618 fit Spicer type 1-3/8" spline driveshaft slip yokes made to accept a press on seal. As far as I can remember, the press on seal was first introduced around 1978 for Ford 4x4 front and rear Constant Velocity (CV) driveshafts although it may have been a couple of years earlier.

Tech Note 3: Original Equipment
Most of the shafts that will have QU40618 Seal as original equipment will be on 1978-1984 Ford full size 4x4 front or rear CV driveshafts and the front CV driveshafts in 1987-1996 Dodge midsize 4x4s (Dakota and Durango).

Tech Note 4: Commonly Used
The most common use of QU40618 Seal is on rebuilt driveshafts. Chances are, any 1957-1990 light truck or SUV driveshaft with a replacement 1-3/8" slip stub/slip yoke combination installed by a professional shop after 1979 will have a QU40618 Seal. Most driveshafts from vehicles built after this era will never require a new slip stub/yoke combination as they use a slip joint protected by a very effective boot instead of a seal.

Tech Note 5: Standard and Optional
Ford used QU40618 Seal on Dana 44IFS and Dana 50IFS front axles from 1980-1982 and on some 1983 models. The Dana 44IFS front axle is found in Broncos, F-150, and standard F-250 models. The 4500 or 4600 pound rated Dana 50IFS front axle was optional on the F-250 and standard on the F-350.

Tech Note 6: Installation
Install QU40618 press-on seal on the slip yoke BEFORE trying to install the Slip Yoke on the splined slip stub. QU40618 are a pretty tight press fit on the slip yoke. However, if the slip yoke vent hole is plugged or you pump grease in at a fast rate, it is possible to force the seal off the slip yoke with your grease.
