S814P: Ford F150 Pickup 87-95/ 3.55:1 ratio/ 8.8/ NL (non-limited slip)

 

thats what i think but like i said you never know lol could be wrong

 

Past thinking, I found the chart. I was gonna be upset if your's was L/S & my 87's wasn't.

well that sucks lol but i guess back to the original plan of buyin this kit http://www.summitracing.com/parts/CMB-14-0065/

 

I was thinking of getting the same kit but im getting the Rickmond Powertrax Lock-Right instead.

 

how much does that kit run? and where can u get it from

 

My 1999 4x4 rear differential pinion seal is leaking real bad. I'm having a hard time pulling the companion flange off of the pinion shaft. Surely the pinion shaft seal does not carry the shaft loads does it? Is there a bearing or bushing that carries the pinion shaft loads where the pinion shaft seal mounts?
