rear block question..

[joshua5438]

I installed a set of Newton 4.5" blocks on my F250. I now have a slight vibration at take off. I have a 2010 F250 CC SB. It has a two piece drive shaft. Newton sent me angled rear block and no carrier bearing. Is this what everyone else has received with this kit? I am working with Jason at Newton to see what we can figure out but I just wanted to see what everyone else has.

Thanks

Is your truck a short bed? I have seen this issue with the 250 short beds. Your carrier bearing is slightly mis aligned. I should shim it.

It's your carrier bearing spacing.. for ever inch you go up in the rear, you need to add 1/4 worth of shim.. I believe that is the correct amount..

Thanks for the suggestions.. After talking with Jason at Newton lifts he informed me that he angles the rear blocks differently if you get them with traction bars. I have not installed the bars yet but he is confident that once they are installed that I will have zero vibration. I should have them in this weekend and I will update this post.

for what its worth, i installed my rear blocks on my truck for my traction bars and the truck ended up going into ford so it went prolly 3 weeks running just the rear blocks without any vibrations without the traction bars on. if you have a 2 piece drive shaft and your stock f250 block is i think 2" so that means you raised it 2.5"s which means your carrier needs shimmed 5/8" according to what was said above^^^^^

did your kit come with flat or angled blocks? Did it have a carrier spacer? Do you have a two piece or one piece drive shaft? Just trying to compaire.

Mine came with an angled block. I have a one piece drive shaft because of the short wheel base I'm guessing so no carrier spacer.

I got the bars installed this weekend and still have a little vibration. Jason is sending me a carrier spacer so hopefully this will solve my problems. I must say one thing about the traction bars.... WOW!!! My truck shifts with the Spartan 300 tune like it did when it was stock. I am very pleased so far!
