Re: upper control arms advice
They are rubber bushings and will be worn out by now, that is unless your 2005 has low miles. Replacing the control arms is easiest and most cost effective way rather than replacing the bushings in the old OEM arms.
I replaced front upper and lower, rear upper and lower arms, and rear track bar, (Moog, Mevotech) along with Moog inner/outer tie rods and the improvement in ride, handling and steering is like night and day. Not only is is much more solid feeling, NVH is lower, i.e. it is smoother and quieter than stock. No bouncing or wallowing around like the worn stock control arm setup. Before it was like playing basketball with shoe laces untied and loose; now the laces are tightened.
