Rear vibration when taking off

Just put on the ultimate lift by toytec. The whole project took me and my buddy 5 hrs. Not as easy as some say but never the less it went pretty well for my first time. The coilovers are huge compared to stock in width and weight. Everything seems to be riding nice except when i take off from a dead stop i get a vibration in the rear. I installed the shims and now wonder if they aren't the problem anyone have any clues?

 

That is a very common problem both on lifted and stock height tacomas if you search for it there are lots of usefull threads people have come up with a few different tricks to help but have it always had luck.

 

How much did you lift? I did a 1.5 inch AAl and 5100's set at 1.75 with the shims and wound up taking them off. I would try removing the shims first and seeing if it is better or worse. Did you install a diff drop? That might be the next place to look. How do your drive line angles look? There are a bunch of links about vibration.

Do a search under drive line vibration or just vibration and you will find some more.

 

take out the shims, and see if it gets better.... if its still there then try a carrier bearing drop...

 

Thanks Doc appreicate your links I think i will try to remove the shims. I have a 2.5 inch lift I think it came preadjusted and they said its either a 2.5 or 3. Come to think of it, she might be a 3 because from ground to fender Im at 38 ".

 

Thanks Etaco I was thinking along the same lines but it does help having someone second the thought. Thanks for taking the time to give your input.

 

No prob.!

If that doesnt work, try both and see if having both helps.... I have just have a Carrier Bearing drop, and still a slight take off shudder.. and have try everything else. so not sure what else I can try....

Just saying, sometimes people just learn to live with it.....

 

You think it will cause any problems down the road? I probably could learn to live with it after all after the muds were put on I have to say goodbye to a smooth ride this baby is growling.

 

haha.. I would try to fix it first... try to atleast make it better. But I really dont think it will cause any damage. the vibe has to be pretty bad to cause damage.. alot of guys have had a take off shudder for 20-30+ thousand miles without any issues....

this thread makes me want to try to fix mine now!

 

I can second that. Just wished there was one fixall for this problem instead of how every truck has different results and solutions.

 

well there is a perminant fix. but it can be spendy.... If you have a short bed, you can do a one piece drive shaft. But that could run some where in the $2-300 range...

 

One piece drive shaft is not a good solution. If aluminum it will not wheel good. The first time you hit a rock it will turn into a pretzel. If steel it will be too heavy.

 

Thread reserect.. lol
Sorry Sandjukie but I got a 1 piece shaft made for my 12, it was stronger and lighter then the stock shaft. With heavy duty life time u-joints. Thing was awsome.
Now im needing one made for my 13'.. got take off shudder that i cant get rid of. Got all my angles good and have tryed everything. This is the only thing i hate about these trucks. So frustrating
