Vibration. Just did pinion seal
Hi guys, any ideas on my rumble after I did pinion seal. Pretty sure I got the load right. What happens it the load is too tight?

I was so careful to mark it and pretty sure I replaced it right. I'm stuck in the house this weekend with my sick granddaughter.
Hopefully tomorrow I can get back under and have a look.
I'm thinking I'll have to take apart and check everything. I'm too old to be slimming around under a truck

Same thing happened to me about 35 yrs ago when I replaced the pinion seal on my 70 Elcamino, wound up getting a salvage yard complete rear end to fix it.
Fast forward to now and my experience in building rear ends, I know the mistake I made back then, I either didn't put enough torque on the pinion nut or too much. I learned over the years how to get it just right and it can't be done by hand, it requires an air impact. I run the pinion nut down until the impact starts hammering and immediately stop, it's worked for me for over 30 years with no issues.
There is another way that involves the use of a special torque wrench, it's a dial type that measures rotational torque.

Well I think I did tighten too tight. After counting threads I backed it off one turn. Do you think that screwed up the seal? Or did I not get the right seal to start?

Replace the seal. I'd be tempted to let a dealership do it. Won't be that expensive and they warranty it for 2 years or 24K miles. If it vibrates after, bring it back.
Word of advice- ONLY USE A FORD SEAL!

Yes I do believe in using Ford parts. Part is cheap and I have way to much time. Repair shops love me. I normally do a job three times before I get it right. �� I will replace the seal and try again. I can't believe how I can screw up a simple job.
Thanks
