Ok so my rear right suspension makes a thumping sound under hard braking and high speeds. Along with over bumps. I had a blow out and decided to check it out. The bushing rite there when you take the wheel off is rotted out. Knucke Bushing I think. With no wheel and the side off the ground if I pull down really hard on my thing where the wheel goes on it seems as if the strut is going all the way out until it stops..like bottoming out except its when I pull it out. It makes a little thump sound, kinda like the one going down the road. What does this mean? Anyways I have all 215-45-17 tires except the tire on this part. It is a 225-45-17! And it dosent do it as bad with the larger tire? Why is this. I think my strut is blown....help me here please. Thanks!

Thanks, Brandon

Oh yeah, and it may not be the strut making that sound when I jerk down on it, could be something else rite there....but it seems to be comming from the lower strut area. There was a large buildup of grease and dirt about .5 inches think that I could wipe off on the strut.

Thanks, Brandon
