Highway Vibes after lifting 2wd ?

Yes. Lower the angle of the drive shaft and it's in about the middle of

 

Okay cool, I first thought this was further rear and would drop my stock height rear even lower causing more of an angle.

 

I would start with balancing and lifting the rear to level (That's if you wish) then move to the spacer I mentioned.

 

Does the tire have to come off the wheel with Road Force Balancing or can the tires stay on the wheel?

Making some calls to find out who has Road Force and a shop was telling me they would have to take the tire off?

 

I am not sure. I have not had the pleasure of needing this.

 

You ever find a fix for this? I have the same issues described minus the lift. I am stock height with 265 70 17 c rated ko2s and get shaky passenger seat and vibes when on interstate.

 

America's Tire does road force balancing and they are all over so cal.

 

Prior to lifting you are supposed to check all angles created by universal joints along the driveshaft, from the transmission to the rear differential. After getting those angles you must recheck the angles after the lift. There is a certain amount of play that those u-joints can safely (within specs) operate at. When you lift a vehicle you inevitably change those angles. Sometimes people get away without having to change the geometry due to where their trucks angles began. It is possible that you aren't lucky enough to be one of those people. You will therefore have to use shims or a carrier bearing drop, or a combination of both to recreate the correct angles, within specification, so that your driveshaft is operating as it was designed to be.

You don't need an ECGS needle bearing replacement bushing because you don't have a front differential, because you are 2WD, so that is unnecessary.

 

Can i use axle shims if the rear is lifted on blocks?

 

I don't see how OP would benefit from this. His rear is not lifted so his drive line angle shouldn't have changed at all.

 

Changing just the front changes the angle of the rear also.
Shims would probably work better though.

 

Noob question.. And probably an obvious one. If I took my spacer/block lift out and went back to stock height, then my driveline angles would effectively be back to oem spec correct? Because I'm considering this now (lifting my Tacoma has been quite the eye opener as to what else gets effected by lifting the truck up, fudging up my rear u joint)

 

Wouldn't lifting the front cause the rear to compress slightly? In that case wouldn't a driveshaft spacer make the angle worse? It was my knowledge that driveshaft spacers are for lifted rear ends because they push down the middle bearing thus straightening the driveline angle. On a squished rear end pushing down the bearing would force your angles to be more out of wack.

 

Correct.

It was just a suggestion, the spacer may make it completely worse for the op.

 

I really did screw up buying the spacer/block lift. I should've waited til I got money to buy a coilovers and new leafs. Now when I go to get the u joints fixed and angles corrected(possibly) it'll all be going off the angles and height from my spacer/block setup. And when I do get new suspension setup later, I'll have new angles most likely and the work will have to be done twice to correct new angles the new suspension will give me. Let this be a lesson to anyone on the forum debating to install a spacer/block lift kit. Don't do it
