Default Rear upper and lower control arms

2004 Trailblazer 4x4, I hit something on the side of the road and bent both my upper and lower rear control arms. I have the Dorman 521-979 and 521-888 upper and lower control arms. Are these hard to replace? I have found much information on front control arms, but cant find anything on the rear ones. Any help would be greatly appreciated!

I've never done them myself. But I cant see them being too much harder then the front, and fronts aren't that bad to do... just make sure to get an alignment after...

Thanks Don! I definitely plan on getting an alignment afterwards. I will give it a shot and see how it goes.

They are apparently also known as Trailing Arms. Install is very easy. 21mm Combination wrench, 21mm Socket/wrench, 10mm wrench or socket, PB Blaster or similar. 2.5 hours total including organizing tools jack stand setup, etc. for both upper and lower. 10mm is used to move emergency brake cable out of the way. Upper control arm front end, pounded out wheel well slightly for better access to bolt removal, and there was no nut to catch when you removed that particular bolt. In and out, simple as could be. I am an amateur and had no problems. Garage wanted $686.98 parts and labor to do the job with Moog parts, I bought Dorman parts from Amazon and spent under $100.00.
