TSB for Tacoma rear leaf pack

1. If you can't get the TSB for free, don't bother. Toyota leafs are overpriced underperformers. I just looked at TRD parts 4u, and even there, they are $432 PER SIDE (they didn't designate whether it is the 3 or 4 leaf pack, but this gives you an idea of the price) If you can still get it free-might squeek by under 36K, get it done and see how you like it.

2. If I were you, I would probably call Alcan and have them make you a custom leaf pack. I don't know where in Utah you are, but Alcan is in Grand Junction CO, you could drive there and pick them up. 5100s are supposed to be good for 0-2" of lift, the dakars supposedly give at least 2.75" of lift.

3. You may end up with drive shaft vibrations, you may not. Lifting changes driveline angles which can throw rotating driveshafts out of balance and lead to vibrations. There are things you can add (shims, carrier bearing drop kits, etc) to try to correct this. Bring it to a 4x4 shop and have them do it. There are no guarantees, some people are more sensitive to driveline vibes than others. If you really want to lift, go for it. If you don't care about lift get a custom after market leaf pack, it will likely be cheaper than Toyota's 4 leaf pack.

Edit: Oh, your truck is an '05, past 3 year warranty. Still worth a try. Good luck.

Hey I was looking at these springs, mainly the 1.5" ones anyone have any experience? Does anyone think they will be good with the 5100 bilistiens in the rear or will i need longer shocks. Or should i go with the 3" ones and set my front 5100 billies to the highest setting. I believe if I do go to about 3" ill have to do the carrier bearing drop. Also is it really recommended to do the front diff spacer drop even if i do just a 1.75" lift.

Oh and Dtacow im not really at the moment looking to do anything crazy on a lift mainly right now I really just want to level out my truck to clear my Toyo A/T 265 75r16 tires, in the process give my truck a bit of a meaner look. And without killing my wallet get the rear leaf springs to fix the noise and get some lift out of them too. Eventually doing a cargo basket on the roof and hopefully installing a ARB whinch bumper. And of course not getting killed by the wife for doing all of this in the process !

Well my 5100 billies came in today. I just replaced my rears and plan on doing my fronts this weekend. They have a nice shop you can use on base that has two wall mounted industrial coil compressors. So it should make life much easier. The rears didn't take me long to do except I did run into a bit of a problem when the top stud on the old OEM shock broke off since there was a bit of rust. I had to take a hack saw to the stud sawing just above the top rubber bushing, that was not fun. At least I got it replaced, next time I use wd40 first then take a whack at it ! Ill post some pics after I install my fronts, I plan on setting them at 1.75 the second from the top.

BTW does anyone know of any good post that show a decent step by step on how to replace the fronts preferably with pics. I read on another post that you have to disconnect the UCA but not remove it in order to make room to remove the shock and coil assembly! Or do I have that worded wrong?
