went to change my control arm bushings and ball joints. ball joint were the easy part. started to do the lower bushings first and as i was pressing the bushing out the the area were the bushing seats started to crush as the bushing started to come out. no problem a little heat move back out. well sounds easier than done. so i ordered new upper and lower arms from the parts place. i all ready bought new moog joints. should i replace the ones in the arms with the moog. i dont want to put the car back together and find out down the road they were cheap china joints. the rubber boot says baw 463521. and do you think i should install the poly bushings i was going to use. thanx for any input on this issue.
