I have an 06 tacoma automatc access cab v6 automatic 4x4 trd pkg.I blew a leafspring on the highway(bad pothole),so i had it fixed by a spring shop and while i was there had them add a leafspring on each side to help sagging while carrying loads.The problem i have now is that i have a "shimmy shake" when i take off only for about 10 feet then it goes away.The spring shop has never had that problem occur in 30 years of adding leafsprings.I went to toyota about it they said all my u-joints and everything looks fine.Went back to spring shop they tried shimming the leafsprings with 1.5 degree and then 2.5 degree shims still have the shake.Someone please help me before i spend any more money trying to fix this.

ok, they removed the broken spring and added "another spring?
were the specks the same?

and if added another to the other side ? then suspect
axle wrap" on takeoff


caused by not having the original specks on the springs

or the rear end is not aligned in the same spot

not a expert here !

I used to have 3 leafsprings per side now i have 4.My rear end may not be aligned in the right spot,good point my friend though one tire stuck out a little more than the other i will look into that next.Any more ideas feel free to post thanks!

just a quick heads up !

if you never measured your bed to your truck, don't just measure the distance difference by that !!!!!!!
it can be off by 1/2 inch pretty easily !

think if you go under you should be able to see dirt/wear marks to do a reference by !
should be able to reference left/right alignment and angle of the axle !!!!! and you should be able to see any difference on both !

IF you have hauled some loads, then look at the bump stops and there should be worn paint on the axle to reference by !!!! and also will give info on left/right and angle !


and you had 1 bad spring??? so just one got replaced and was it a good match ( spring rating) and new helper springs? if different ratings could be a problem? as one is 5 years old and one is new

if you play with adjusting it, BE SAFE !!!!

check hydraulic lines and use good jack-stands ! hydraulic lines to make sure you don't crimp or damage one had now have brake trouble, good jack-stands well think you can figure that one ;-D

just a OLD hotrodder that discovered wheel hop and how much fun it can be to t-shoot
tires/springs and axle wrap after "upgrading tires and engine"many many years ago
don't know if they still sell them or call them the same but "traction masters" fixed it

Had many people look at it and everyone is stumped,trying a 4 wheel alignment to see if that helps.

Had alignment done still shaking.I offically have no answers for this problem.Please god send someone to tell me how to fix this.

Try greasing your Splines on the rear drive shaft real good. I have heard of that being a problem.
