front lower control arms...I am thinking of going with Tereflex ones....how had is the install

 

2 bolts. Remove, put the new arm in, replace bolts. Do the other side. If you have it jacked up, wait until it's on the ground to tighten the bolts.

Check the Adjusting Caster section of the alignement write-up for some tips on lining up the bolts.

There is also a Teraflex 4" install write-up with the step by steps for their arms... (steps 12-14)

Its super simple - only takes a few minutes to do - maybe a few more your first time.

Don't forget to grease!

 

it may take a little finesse to get the bolt holes to line back up. other than that... piece of cake

 

Do 1 arm at a time, don't try to take them both off at once.

 

you will be happy with those arms. They are built tough as nails and look nice as well. The increased caster really makes a huge difference in the way it drives. They are well worth the install effort and cost.
