Cornfed Install/Yaw-Sensor Info

Hi All,

I know everyone is probably sick of Cornfed-spacer lift posts, but I also know that I read each and every one of them before deciding to do mine.

I was tilting towards removing XREAS and installing Donahoe coilovers and new UCAs along with new rear suspension but decided to try the spacer lift first due to cost.

So far I'm very happy with the lift. The ride is a little "tighter" on the streets which is to be expected and I definately like the new stance.

One thing that I didn't read on the forum anywhere was about the need to re-center the 4Runner's yaw-sensor after suspension work. When I first left the shop, the VSC (Vehicle Skid Control) light was on and would not got off. After about 10 minutes of troubleshooting, the techs found that the yaw-sensor needed to be re-centered after the installation. Once that was done, light went off and we were good to go.

Now I just need to get those Dunflops swapped out!

First picture is after, second picture is before.....

yaw sensor? ?

what is that?

Good question....I could give you a really technical aviation description but applied to cars it's the sideways movement of the vehicle...like when you are on ice and the butt end starts to lose traction and slides to the left and right. The 4Runner has a sensor that detects this and engages the VSC system when necessary.

Here's a good diagram of how yaw affects an aircraft.

I suspect that the problem was just unique to your particular 4Runner. Plenty of guys here have lifted their 4Runners without any yaw sensor issues at all.

My own lift is just one inch in the front, and it rides and drives exactly like stock without any yaw sensor issues.

Has anyone else even heard of needing a yaw sensor adjustment after a lift?

....you mentioned they found a disconnect for the xreas?? any idea where that is?

Yep, if you follow the X-REAS line from the shock to where it enters the frame rail, it's where the airline meets the hydraulic line...there's a check-valve where you can disconnect. The techs figured that out by using the Toyota service system (All-Data).
 
Looks nice. You'll have to give us an update after a couple months of driving it.
Wonder if you need to adjust the headlights because of the front-end sitting higher?
How much did they charge for install?

Thanks. I really like it so far. I do need to adjust the headlights down a bit....may do that tonight. I paid $400 for the install after all was said and done. I'm a bit embarrased to say that since I've read many other people on this forum have paid much less (or at least that's what they say they paid). Even though I paid more than most, I'm very happy with it and feel that I could take it back in a second to have them fix any problems. I did price many 4x4 shops around the Denver area and they are all about the same.
 
Looks good! I think that is what i'm going to be going after too, for my 4Runner. Where did you get it installed?

Random question - how is your 4Runner in the mountains? plenty of passing power, and are you able to fly up, say, vail pass?

Hi Boulder4runner. Thanks! I got it installed at All American 4x4 in Littleton. Great guys and they did a good job. After having it about a week now, I can say that I'm very happy with the handling. The new height is great and my friends that see it in person think it looks great.

I love my 4Runner in the mountains. The V8 has loads of passing power and yea, it feels like your flying right up there.
 
That sure look high for the 2/1 combo. Looks good though. I have a 1" front waiting to be installed. I thought about switching to the 2/1 , but not sure . Other than the looks there are no real benefits except 1" more clearance under your front bumper.

Hi Falls. There is a definate increase in height and about 2+ inches of clearance on the front bumper with this kit. It's exactly what I was looking for though as I've been in many circumstances off-road where those 2 inches would have come in real handy.
 
Update....after a few weeks with this lift I couldn't be happier. The suspension actually performs better (in my opinon) and is more responsive. While I had many reservations about lifting my Runner....I'm very happy I did:)
