upper control arm write-up
Ugh, have fun with the devil bolt! There is a bolt that goes through a "knuckle" that holds the 2 upper control arms... that bolt.. is no fun. Be prepared to drill it out, and have a couple 10x100mm bolts handy to replace them with. 10x100 with about 75mm of shoulder, and only 25 mm of thread.
It's not that bad of a job. the pinch bolt is the biggest pita. i used pb blaster when i had to replace el bolto del diablo(the devil bolt). took a little while but it came out. did them at 157,000 miles. even the devil can be beaten. but the def. will be in no shape to be reused, for anything ever. But basically, remove the pinch bolt, the bolt holding the control arms towards he inside of the car will come out no prob., but the other one towards the front of the car, unless yours are in diferently, you will have to remove the entire shock/strut/spring assembly. there are three bolts in the engine bay that hold it on and one big bolt on one of the lower control arms. there is also a thin wassher hold the assembly up, so when you unbolt it from up top, don't be surprised that it doesn't drop down, find the little washer in the wheel well and pull it off. carefully knock the bolt off of the lower control arm that holds the shock/strut assembly in and then pull the assembly forward. now you will be able to take the bolt out that you couldn't (and the reason that you can't is when you get loos to pull it out, it will hit the inner parts of the wheel well body, there was no way arround it for me. VERY IMPORTANT: REMEMBER THE ORIGINAL POSITION THAT THE CONTROL ARMS WERE IN, THEY NEED TO BE PUT BACK IN THE SAME POSITION. when i put the back in the control arms towards the front(you know the one that the susp. had to come off for) i put the bolt in the other way, so if i ever have to do these again i don't have to remove the susp. to do it. it will be fine. to get the susp. assembly back in place, you will have to carefully pry in between the lower control arm and the bottom of the shock. after that, just assemble the rest as it came apart. don't pry on the gaps where the the controls arms meet, you know tthe pinch bolt and avoid pounding on the arms, just patience, wd40 and pb blaster, if you have no wd40 that is fone but def. get some pb blaster, there is a big difference, it will make your life alot easier doing this job. it will be alittle tough to get the new controls arms back in where the meet on the hub assembly, just wd40 it and work it in. sorry for no pics, i am on break at work. hope this helps
^ ^ yep! After the devil bolt, it'd be clear sailing! My car had like 55K miles on it when I did them, and one had to be drilled out. It was about to break, as the head was turning, but the other end wasnt. CRAZY. I should post a pic of the bolt... good times :P
thanks, i just looked and the bolt by the springs is facing the more convienent direction, THANK GOD!!. so i wont need to remove the upper controlarm bracket. hahahaha!!!!
But the hell bolt is hell on my car as well, looks like im gonna need to whip out the sawzall and the grinder, DOH!
where did u guys get new hardware for this?
