Okay, so I just installed the 2.5 Dualsport AEV lift yesterday. HAven't yet changed out the tires, so it is still sitting on the stock 17" rims with wranglers on them... So, as I come to a stop, at least on the mountain from about 50mph, it sounds like the tires are rubbing, only when the brakes are engaged and coming to a hard stop. I don't hear it on flat, but slight incline will do it.
Anyone know what might be causing it? I've looked and I don't see any rub marks anywhere, and because I have tons of space under the Jeep now, esp. with the small wheels, I can stick my head in the wheel well. It doesn't happen all the time, but mainly when I come to a hard brake on a slight to higher incline...
im not sure if you need the wheel spacers, if you look at the clearance in the rear at the sway bar links and the sway bar itself, it could be the foward motion causing the rear to shift and rub in the rear. I have the 3.5 lift and def need spacers.
If it aint dead kick it, if you kick it and its still alive, there's always a baseball bat!
i am assuming that the 2012's are the same setup underneath as my 2007. stock rims do not have enough of an offset to clear longer rear sway bar links. my bet is thats where you are hearing the rubbing from. 3 solutions- buy wheel spacers, buy new rims, or take off your rear sway bar end links until you can purchase one of the above mentioned options. personally i am not a huge fan of the third option on a coil suspension but i hear alot of guys do it just be a little more cautious in the corners.
cross threading is as good as locktite!
Well, I looked all over and haven't found any evidence of rubbing. I haven't checked the rear, however, though the sound is located near the front. I will check in the morning and update - But, I think spacers might help.
As for the brackets, it isn't needed, but it returns everything to the stock geometry. I am trying to reduce the risk of speed wobbles, as I've had them before. My offroading needs are minimal - simple ungrated fire roads and bush whacking to get to rocks for climbing amd/or hunting, so the complaints about them getting in the way for the 2.5 I don't anticipate having an issue. Not a rock crawler at all...
If you are using the stock bumper look at the front lower air dam. Since you think it's comming from the front.
I looked under mine ,granted I'm running an offset wheel but I don't see anything in the front that could rub. Maybe your brakeline if it isn't tied back enough.
Also I though the front geometry bracket s were not needed on the 2.5.
It seems to be hit or miss with 2.5" lifts.
When I ran a TF 2.5" lift, the change in caster (to me) was definitely noticeable -- my JK was flighty at higher speeds. Any faster than 60mph required two hands firmly on the steering wheel at all times and even then, it still felt like you might drift into another lane.
I looked all around and it doesn't seem that there is any way the tire can be rubbing. I find that it is only when there is some compression, in other words braking hard causing the front end to dip, or going over a low area hard to cause the shocks to compress -- I hope you get the idea.
The only possibility is the brake lines. I tried to move them out of the way, and it still does it in the above circumstances. I will recheck the instructions and see what I Can find.
Anyone with the 2.5 AEV lift have this problem on a 2012?
Well, I take this as one more vote for my RK 2.5" lift.... Stock wheels and tires and you're having issues??? Why would spacers be needed to run stock?
And that being said...spacers here in Utah are illegal, so what do you do then?
I can see with the 3.5" kit maybe, but the 2.5? I seem to recall another thread a few months back complaining about AEV's 2.5" kit, can't remember the exact issue though.
