I just got a 3.5" Skyjacker lift put on my Sahara and the day after I had it put on the ESP BAS light came on. The tracktion control light comes on as well but that can be turned off with the button by the shifter. I had read a thread that said after a lift if your steering wheel isnt strait it will cause the ESP BAS light to come on. Does anyone know how to straiten the steering wheel out? It only needs to go a little bit to the left. Is that the answer to fix this problem? If you have photos to direct me it would be much apreciated im not the brightest crayon in the box...


somthing strange noted... after this problem started I noticed when you put the key in the ignition where it usualy shows the mileage before you crank it over it now says 9ATE...???? Anyone know about that?

Thankyou

 

You need to adjust your drag link to center your steering wheel. Search "drag link" and you'll find a few threads, some w/ pics.

 

send the money and get a allignment

 

Go to this link and check out step #57. The "gate" means your back door is open!

Get a wheel alignment! Everyone told me that I did not need one after the lift. ESP light kept lighting up around on and off ramps on the HWY. I got a wheel alignment and have not seen it light up yet. Be sure you go to a good shop that will take there time mine took an hour and a half to adjust everything.

 

i had the same lights come on without a lift. i haven't even taken it wheeling yet... nothing out of the ordinary as far as regular driving either. what would cause this???

 

Please save your money and DON'T take your Jeep to an alignment shop. Because of the new design of the steering system on the JK's, your toe-in will not be effected by the lift. And, even though your caster might be off a bit due to your lift, it cannot be adjusted without cam bolts (which I do not recommend) or adjustable upper control arms. Also, camber is an adjustment that only IFS vehiles have to deal with. So, the only thing for an alignment shop to do is to re-center your steering wheel as has already been stated and that is a simple 5 min fix that you can do by yourself and a 15mm wrench.

 

Dont the axles have to be centered after upper and lower control arms? How can that be done correctly without an alignment shop doing it. Just asking.:confused:

 

It'd be nice to have them re-repositioned under your Jeep but not necessary unless you're up really high.

Well, depending on how high of a lift you have, all you need to do is extend the lower control arms so that your bump stops are more or less centered within the coils again and not rubbing the side of them anymore. Then, you just need to set your uppers so that your caster is set to the appropriate angle. On a 3"-4" lift, I would recommend about +6°-7°. Because your front drive shaft is so long and the front axle is now an HP, the pinion angle will most likely be okay +/- wherever you end up here. Of course, to do any of this you will need an angle finder and some tools but it certainly is something you can do yourself. And, if you only have a budget 2"-3" lift (i.e. no adjustable control arms), you'll only need to worry about re-centering your steering wheel.

 

Got it! Thanks for the info. I did a 4" Teraflex in my situation it was much eaiser having it fine tuned by an alignment shop. It stopped my ESP Light.
