I need to thank the Crew at 034 Motorsport since they were able to split a kit and sell me only the lower control arms (I have the Sterns on top).
These have stiffer bushing and going to install them in few days. I'll post a shot DIY

The DIY

The process is pretty straight forward
1 hour per side

Tools

2 x 18mm wrenches
10mm wrench
Hydraulic floor jack
Ball joint separator

FRONT ARM

1/ Disconnect auto-leveling clamp if installed
2/ Lift the forward arm with the floor jack few inches to release the sway link pressure. Remove the upper bolt of the linkage
3/ Remove the shock bottom bolt
4/ With the ball joint separator, free the arm from the hub.

DONíT EVEN THINK STARTING THIS JOB WITHOUT THE SEPARATOR!!!

Got mine from Harbor Freight ($10) but I had to enlarge the fork because the cutout was too small for the pivot cone widht. When it releases, it sounds like a shot gun!

5/ Using the 18mm wrenches, remove the inner bolt. Replace the arm

REAR ARM

1/ with the ball joint separator, free the arm from the hub.
2/ Using the 18mm wrenches, remove the inner bolt

You will not be able to slide out completely the inner bolt with removing the 10mm plastic nut holding the cover. Remove the nut and bent down enough the plastic cover to make room and slide out the bolt.

You had adjustable uppers before right? Did you feel a big difference when upgrading the lower arms w/ stiffer bushings?

Definitively and even if still good at 95000 miles, the larger bushings were totally distorded

Replacing all my arms tomorrow. Anyone happen to have the torque specs and do these need to be loaded like the uppers?

Mine seized and I had to take off the spindle and get the arms pressed out

Going to do this tomorrow, how much surface did you have to remove from the tool to make it work?
