98 ZJ Stock Lower Control Arms

I am trying to install a 3.5 Lift onto my ZJ (first lift) and the bottom bolt on the stock lower control arms just will not budge whatsoever, so I am just looking for some advice on breaking them free and if this is usually a trouble spot or not on the ZJ's. Any light shed on removal of the control arms is greatly appreciated, thanks.

Try heat, rust penetrator, more heat, and a cheater bar.

Let it soak overnight too with the rust penetrator.

you're gonna need a 2 ft 1/2 dr breaker bar or similar size or an impact wrench, and possibly heat.

yeah you can i have them on mine, the only thing is the back wheels are really close to the front of the wheel well. and for some reason i rub my front left tire only when in reverse going down a hill. but you can do it. it rides fine.

im not running that lift but from all my observations youll only be able to run like a 31" tire with stock control arms, proabably 33" tires if you change them out

had to cut off one of the front LCA bolts. It was a HUGE PITA and the replacement bolt from the dealer cost a lot.

that is an eccentric bolt or cam bolt it think its called.. that is what is used for your caster alignment. PB Blaster it overnight, then only apply your torque from maybe an impact wrench or BFH /breaker bar to loosen it on the nut side. If not you impact the bolt head side , the chance of breaking the cam bolt is greater.

When i replaced mine I followed the advice posted previously.

Soak it with PB Blaster a day or two in advance. And then I used a 3 foot cheater bar. It was easy.


(Now putting it back together was a pain. Couldn't get the bolt holes to line up right had to borrow a friend to help get everything in place.)

Yeah itl probably be rear upper and lowers. I have about 3 inchs of room between the front of my rear fender and tire. Like I said with the 31's I only rub the front of my left front fender in reverse going down a my driveway Right as I make the transfer from my pitched driveway to road,and it barely touchs the tread. Trimming to clear 33's shouldent be much.I also need upper and lower front control arm bushings so that probably has something to do with the little rub. As for buying new control arms, IMO don't waste money on the fixed ones just buy the adjustables so when you decide to go bigger later you can easily. IRO makes some pretty good ones and are not too expensive. Last time I checked it was 300 or less for upper and lower rears. If you haven't already I'd invest with in a rear track bar as well as a front one if you didient get it with the lift.

I am curious on wich shocks you got with the kit though? I got the doetsch tech and I love them but the only thing I hate is how much they limit flex.
