[TR] TR3 pinion seal question

[Angelo Graham]

Hello List:
Noticed after installing a new pinion seal on my Girling axle that 
the seal seemed to have a lot of drag on the pinion shaft. It is a 
new, modern seal sourced from the big 3, but it was very tight and 
now I can notice a real drag on the shaft when I turn the drive shaft 
flange. Is this to be expected? We used lots of lube to install the 
seal and it was a tight fit.
Worried about eventually wearing a grove in the pinion shaft - 
Speedi-sleeve time again.
Any insights??
Thanks in advance for any advice on this.
