New owner with a few questions

[Hefel86]

Hi everyone, I've been searching on the site for quite awhile over the past 6months while looking for the perfect truck I wanted to buy. Well over the weekend I too the plunge and bought a 2000 f250 cc 4x4 8 inch lift with only 80k on the clock. As for the price it was a deal of a life time! There are a few thing that need to be taken care off mainly the clock spring. My main question refers to the slight shutter at take off and only last about 20ft. Will shimming the carrier betting with some flat stock help with the vibration? If its drive shaft related... Sorry for the long post and thanks in advance

Welcome to the forum!

While I am not the expert on this subject, I will let you know what I've experienced with my truck until someone more knowledgable chimes in.

My truck has a slight shake upon take-off that lasts about 20ft as well and then from 47-49mph there is a little shake/bounce. I started off by having the tires rotated and balanced. No real help there. Next I took it to my local trusted mechanic and had him replace the U-joints on the driveshaft and put a new carrier bearing on. He then drove it with me and agreed with me there was still a shake and sent me to his driveline guy. Took it there and the guy looked at my truck and showed me the big factory balancer on the driveshaft from Ford and said that I was lucky it didn't shake more than it does.

Since all of this I have basically learned to live with it now. Sorry for the lengthy post with no real answer, but it may help you out with a starting point. Again, welcome to the forum. There is a lot of good knowledge here that repeatedly helps me out. Welcome to owning a Powerstroke too! I love my truck and wouldn't trade it for anything!!!

Thanks for the reply. Yeah the shutter isn't a huge problem just one of the things I'd like to get taken care of if possible. No one that rides with me has noticed it but I can feel it in the wheel just at a take off

I guess I should also state that the truck is bone stock other than a 4 inch exhaust

I forgot to mention that with your 8" lift, you may want to start by shimming the carrier bearing. Some say it's necessary, others say it's not. I have 6" lift on mine and no shims. Personal call I guess.

Shimming may help but best fix is adding a CV after the carrier bearing..

dont mean to be a downer but my f150 had a shimmer and it was the tranny.... but it might not be im no mechanic or professional

[Hefel86]

Got it it fixed. I tabbed up a spacer out of a 1/4" piece of flat stock. I have another question, will an 8" lift rob some power from the 7.3? I know my engine is stock, but it seems like I should have a little more acceleration. Probably doesn't help having 37" tires

Lift isn't going to rob power, but the tires will! If you have 3.73 gears, that's a tall tire, 4.10's would help get things back to where they should be... I have 35's on my red truck, and it's a noticeable power drop over the stock 265's, even going up to just 285's was noticable.
