Couple of Problems

[jeshoyt]

I was afraid I'd need to chuck the k&n. It's funny as heck, I tell my buddies what I am hearing on these forums and they defend that k&n 100%! They don't really want to hear that they don't filter as well as others do(obviously because they have them in their vehicles). I mostly drive my truck on oiled roads but I take it up hunting and fishing on dirt roads frequently. It's not like I'm off roading or anything, but letting dirt into the cylinders makes me cringe. It would have helped to do a little research first! That K&N is gone.

Thanks Marc, and I'll let you know what I find out about this support bearing. I am sure I will have to shim it like you said but that old bearing just looks and feels really worn out. And what's to say that the new one won't eventually do the same thing. Can I shim it while it's assembled or do I have to take the drive line off?

the shimming is pretty dang easy..just undo the two bolts holding the carrier bearing to the frame crossmember.....put the shims in, and bolt it back up. If by chance you "run out of bolt"...which ive only seen on lifted trucks.....you would also need to get a longer boldt with the same thread and pitch to use the same J nut.....but i doubt youll need to shim more than a half inch...

I would go with the Air Aid, the filter you need is #700-469 and
it's about 50 bucks. You can also get a prefilter for it if you
need it...

I replaced the carrier bearing, and the other one was pretty rotted, needed to be changed but I am still getting some vibration when I get on the gas.

I called Ford and the parts guy said they don't make a shim kit for my truck? I am going to have to call around it to find one looks like. Marc is the man. I REALLY hope the shims work (that is, if I can find them of course). That vibration is pretty annoying. How come my buddy's super duty doesn't do this?

Thanks again Marc!

Think I found the shim kit. $52 from Donahoe. Should have looked around a bit first.

I got the new Carrier bearing installed, then shimmed it down about 1/2 inch. Used some 8" strap from the hardware store for $8. Vibration gone now, no clunk. Thanks again to Marc for the idea!

[mschn99]

glad to hear you got it fixed!!!!

one thing to remember though, when you pull a trailer that vibration will come back, if the trailer is heavy enough to change your driveline angle. The vibaration is a nusance, but not hurtfull to anything.......you can only fix it to not do it either loaded or unloaded...its rare to have a truck that doesnt do it one of those ways.....some guys just dont notice it....

Would it help to install a set of trac bars?

I have an AFE Stage 2 filter system...what a difference. what i like about afe is the optional higher filtration filter you can get and i was told, by a AFE rep, that you only loose about 50 cfm which is somewhat noticeable but still much higher than a stock filter system. Prefilters are nice but they mainly just keep water out of your intake. Ive heard bad things about k&Ns especially here in montana...marc can vouch for that. One thing that is esspecially cool about the afe, and im sure the other ones do it, is that when you get on the throttle then snap release it you can here your turbo let off and its quite loud. That is somewhat bad for the turbo but i haven't heard a turbo bark yet so i don't know.

if you want to minimize your drive line shudder, ive found replacing the 2 pc driveshaft with a solid one helps alot. you can do it as long as you dont have a lift bigger than 8".


ive also got the k&n setup, and im thinking really hard about ditching it for the afe stg II.
