Just curious as to what all tools are required to change out the upper and lower control arms? Socket sizes and tools etc. Thanks!

Good morning,

You will need 1/2 drive sockets from 12mm to 27mm. You will need 1/2 ratchet along with various extensions.

You will need 3/8 drive sockets from 8mm to 19mm as well. 3/8 ratchet and various extensions.

You will need a tuning fork with a good dead blow hammer.

Floor jack, jack stand as well.

White out to paint where the marks are for alignment as well.

Big job.

Roy

What is the tuning fork used for? Thank you for the much needed information! Also, the airbag suspension has been replaced sometime or another with the conversion they make for them, do I need a compressor for the spring? I wasn’t sure on that part. Thanks!

No, once you disconnect the struts, which is what I believe you have, it will not need to be compressed as it is part of the strut.

You are welcome.

A tuning fork is used to release the ball joints from the spindle once you loosen the nuts for the ball joints.

Could I just use two hammers to “shock” the ball join out? (Smacking spindle between the two hammers)

You could. Just be very careful you do not hurt yourself.

Got another question. How do you go about replacing the lower control arms? I noticed my torsion bars run into them. Seems more complicated than the uppers. Anyone have a repair guide for this? Thanks.

You can do it without the tools but it will be much harder. You will need a tuning fork to release the ball joint. The torsion bar will be difficult to remove once you release all the tension without the tool. It pulls straight back buts gets stuck from age.
