I'm pickin up bad vibrations...

[Mooseknuckle]

ok my TB is a 2006 with about 54,000 miles. after it was lifted (about a year ago) the same place mounted and balanced the tires and did an alignment. About a week ago Mario and I replaced the springs with 87's and put Mrks 1/2" shims in. When i take off slow I'm good,but when I push it a little the front end shakes then dissappears at around 25-30. So I went to get my front tires rebalanced which I thought was the issue and the guy showed me that I had no weights on one tire it was all outta wack. Seemed to be gone for a day now its back weights are still in place. Is it possible it could be the tie rods already at 54,000? Could it possibly be some loose bolts or something? I'm getting an alignment next Friday after Mario and I replace the driver side cv shaft. Thanks!

You need a new alignment. I had similar issues when lifting the front more. Any change to front suspension demands an alignment.

Especially if you just flipped your UCAs and you have tires with sidelugs.

[Mooseknuckle]

ok guys thanks I appreciate it. I didnt flip the UCA's yet but I'm gonna once the weather warms up.

[HARDTRAILZ]

Flip them now. 20 minutes. Or you get to pay for another alignment.

[Mooseknuckle]

I will...lol I know I dont wanna have to do it twice right..thanks

HT and I see differently on this, but I could almost guarantee that it goes beyond an alignment. I bet it is your CV's vibing due to slight bind from the added lift of the shim and springs.

Mine has been aligned and with just a little extra height added to the front end it will vibe if I gas it from a stop. I just had to finally drop my front end down an inch to get the vibes out of it. All smooth again but I miss the height.

And werent you asked what lift you were running since it was claimed to be far different than mine? Did you ever divulge? I looked and didnt find a build thread.

[bdp1978]

Yep, Ive discussed it quite a few times that I have a readylift (Outside the strut), also that Ive never been completely happy with it although it works fine as-is.

Overall it doesnt change the fact that if you push the lift too far you'll get vibes from the CV's. An alignment wont fix CV vibes, which reading the conditions that they changed on the truck (Shims and springs) had the tires re-weighted etc. leads to the point that under hard acceleration he is most likely getting binding in the CV's that's either from the tripots or likely the motormounts.

[fishsticks]

I still have a very slight binding of my CVs at full extension. I lengthened my front strut assembly by a pretty good size (11/16 in). This does NOT cause the front end shake. My front end doesn't shake.

The Readylift lengthens the strut assembly considerably... probably enough to put the CVs in bind if you add any other lift to the front end.

Moose is using Marks lift IIRC... he's not in the same danger of CV bind as you or I unless he's extended his strut assembly beyond what Mark's lift does.

[bdp1978]

I was just throwing out another point to look at due to the spring/shim change he made - which resulted in an increased vibration. I know when I have experimented with increasing my lift by 1/2-1" that it will be fine if I slowly take off or am up and running. But if I accelerate hard it will give me the front end shimmy shimmy.

Just some other experience.

[HARDTRAILZ]

Alignment...no shaking for me with Marks new lift. Seems the readylift is the variable that creates shaking.

[Mooseknuckle]

I have the 2" BDS lift with Marks 1/2" shim and now 87's. To me it looks completely level I have yet to find level ground in this freakin state to get some accurate measures. Brad thanks for the input. I'm not sure that I have maxed out so much that my cv's would bind and cause shaking. Marks lift provides 2.5" of lift and with Marks shim so does mine there are others on here that have either Marks or my lift with and without the shim and the stiffer springs 87's or 88's. They dont really have a problem which leads me to believe it's either an alignment or the tie rods. Hey you could be right and if all else fails I will take out the 1/2" shims. I have to get an alignment anyway.Either way I will keep you posted

[Mooseknuckle]

Damn twenty minutes?! Thats good I was looking on the driver side that one bolt towards the battery doesnt look fun,Mario pointed that out to me...so whats your secret?

Cut the fenderwell.

[bdp1978]

Just trying to provide an extra example to think about

For the record, with the readylift and an inside the strut spacer I never had any vibes either - with the stock half shafts. It was after I switched to an aftermarket half shaft on the drivers side that I got a vibe under hard acceleration and had to pull the inside spacer and just run with the readylift.

[Mooseknuckle]

ok so it was due to an aftermarket cv half shaft replacement? I havent replaced mine yet not til wednesday and that is due to a torn boot,I was gonna change the half shafts anyway with cardone like everyone else on here. Which half shaft did you get? I totally see your point and I appreciate it.

[fishsticks]

The Cardone shafts have been reported to be less tolerant to steep CV angles in the past. I would just get a new boot if you can.

[bdp1978]

Like Donny just said, at this point pretty much all of the aftermarket CV's are proving less tolerant of angles than the stockers. I would get vibes if I had a lot of weight in the back, or a trailer hooked up etc. When I accelerated hard, but after the assembly swap it got worse.

My whole point in this discussion is that I've always been taught that if everything worked properly before you either changed or "Fixed" something----and then afterwards it doesn't work the same - that the most likely cause is in something you've changed. Getting an alignment will certainly never hurt anything, so hopefully that clears up the issue for you.


Sorry for any typo's - responding from my phone.

[Mooseknuckle]

where is a good place to get a neoprene boot? I guess I have to do more research cause I havent come across anyone saying anything bad about the cardone replacement half shafts. Obviouisly it would be easier and probably take less time to fix. Thanks
