Make sure you have all the correct bolts for the control arms. My upgraded Meyle set had the correct number of bolts, but I was missing the bolts for the shocks. I had an extra set of bolts for the upper control arms. Also, the bolt that secures the 2 upper control arms (ball joint end) is difficult to remove if you live in an area that uses salt on the roads. I put penitrating oil on for several days and still had to heat it up with MEPP gas to remove this bolt. The threaded bolt on the tie rod ends tend to rust and one of mine was frozen to inner tie rod. You need a 38mm or 1.5in crows foot (donot get a 12 point, it will not work because the nut has rounded edges, I tried a 12 point from work and it did not work) to remove the inner tie rod if your outer tie rod is frozen to the inner. I had to use MEPP gas again!! When I did my control arms I drove my car up on ramps, jacked up one side, removed tire/ramp and supported that side with a jack stand. The car was high enough so it was not to difficult to change the control arms. Make sure you have a breaker bar to brake loose rusted nut/bolts. I did the control arms in this order: Rear lower (remove/install), front lower (remove), uppers & shock/spring (remove/install), front lower (install). The new HEAVY DUTY tie rod ends really helped my car alot. I can feel the road!!
good luck
