My 5th gen 4runner with a toyotec front suspension 3 inch lift has always pulled to the RIGHT since I got it lifted. (If I'm going 60mph and let go of the steering wheel I've done a full lane change in 4 seconds) The 4x4 shop that did the lift never could get it aligned. They told me their guy called in sick for a week, another time, he was fired, another time, their lift broke, another time their new lift was not installed etc. This has gone on for 3 years. Long story short, today I was told to measure from top of the wheel well/flair? ..... to the middle of the actual wheel. The left front side height is 23" high and the front right side height is 24". I"m pretty sure something was obviously installed wrong. Does anyone know what was installed wrong and does it make sense that the 4runner is pulling to the right? (I would think the left being lower would pull the truck to the left? but it's pulling to the high side, the right side) Thanks for any ideas. I've taken my 4runner to so many shops, wasted thousands and I would think one side being a full inch higher is basic 101 troubleshooting.

I have a 3rd gen with a toyotech 3" lift and it pulls right and somewhat leans towards the driver's front as well. The good news is that your suspension is most likely not installed wrong. If it was there would be a lot more wrong visibly and audibly. The thing about the leaning to one side is that the front driver side most consistently has the most weight, obviously from the driver. Also, your gas tank is on the left side of the vehicle. At 23 gallons, that's almost 140 pounds on that side. Over time (a matter of years) the suspension tends to sag a bit where its been used the most. I had a 96 4runner with stock suspension did this as well as my 99 4runner with just a few year old lift kit. If you have been off-roading or have any gear, that would extintuate this lean as well. As far as the tracking, I would just get another tire shop to re-align your vehicle. I would also get them to inspect your suspension to make sure nothing is wrong with it. My word is not fact but just something to think about.

Have alignment checked at a competent shop willing to do the work right away.
Possibly and most likely (from my experience in the past), the tie rods might need some fine tuning as the passenger tie rod might be too extended, or the driver might be too pulled in.

Other factors that might cause right pull.
Brake dragging on the right side.
Uneven tire wear, tires on right said causing pull.
Road crown.
Unequal tire pressure.

Depending on the lift, a few more small things to look at:
1. Shim the driver's side with another 1/4" shim to even out the lean.
2. Take a look at the panhard bar in the back, make sure you don't have too much angle going on there. It can pull the rear end over to the side and effect the entire system.
3. Long shot, but check the installed springs and make sure they match. A higher weight spring may have made its way onto your truck by mistake.
4. Get all of your bushings checked. A worn bushing can effect the entire system as well. A bit harder to diagnose if a shop is not specifically looking for it.

Best of luck with your search for a solution. It can be frustrating (especially after 3 years!) But once you have found the culprit, it will make you love your rig again.

Look up "driver side lean".
Very common with T4R and Tacoma.
Probably as many fixes for it as threads.

Are the toytech coils adjustable?
If so crank up that drivers side some or back off the passenger side some.
1/2" adjust gives a 1 inch lift ratio.

Something that seems to get over looked and not discussed.
The OEM coil springs, at least on my 2004 T4R, the driver side had an extra coil and is a thicker coil (diameter) factory compensation.

If that shop cant do your alignment take it to someone else.
Another common thread is "siezed cam bolts"
Makes it hard to get the alignment right if the cams are basically welded together.
