I was going to start a Vibe story post like this one, but after seeing this. It's perfect for it.. here goes.
I have an 09 4x4 TRD with stock wheels. I installed OME 886 coils with spacers to start - Truck drove pretty well but the steering wheel was jumpy and I could feel every crack in the road.. at high speed there was some minor vibes.. but it was expected.
ADDED TSB AAL - Back end went way up in the air.. HORRIBLE vibes.. the gas pedal vibrated so much it would make my foot kind of number on the long drives. it had a Shudder from stop to start at 5-10mph and really bad when coming to a complete stop. Worst felt when in bumper to bumper traffic.
CARRIER BEARING DROP - Seen here http://www.tacomaworld.com/forum/tec...k-you-too.html
got the idea this would fix some of my vibes.. IT DID! worked great for the majority of my Driveline vibes.. although my hands were going numb driving 60-65 be this time. high recommend this one!
LR UCA INSTALLED - Wow.. this helped a lot too, but still not perfect.. read about it here - http://www.tacomaworld.com/forum/2nd...alignment.html
After I put them in, it was a round and round with the Alighnment place to get it perfect.. once it was.. worked great! but still had vibrations..
TIRE BALANCE - truck only has 7000 miles on it, so I never considered this but after reading more online.. I said what the heck. Read here: http://www.gadgetonline.com/Vibratio...duction:%C2%A0
went to two discount tires to get this done right.. again, HUGE difference when done right. but there was still some vibration.. very slight. but I am a perfectionist when it comes to what I feel in the steering wheel.
REMOVE FRONT 10MM OME SPACERS - I did this last weekend with yotarob2005 and it was the final piece of the puzzle. Apparently, i had more than 3" of lift in the front with the 886 coils (STOCK 4WD FRONT END) and the spacer.. took the 10mm spacer out and my CV boot angles were nicer to my liking and the Vibe just Disappeared.. I still have a little more than 3" in the front.. but I was closer to 4" with the spacer. FYI - I have done no Diff Drop because of what I read about it on here.. seemed to me more people noticed Clunking after doing it although certainly not all.
it was long winded, but hopfully it will help someone out there..
