Replacing my coilovers - the old bushes were about 48mm and the new ones are 50mm which doesnt fit.
Can anyone tell me if the piece in the picture is fixed or is it supposed to slide to accommodate different sized bushes?
Mine have always moved without a lot of persuasion. A bolt just short enough and some good thick washers or maybe a long all-thread is probably best. But in a pinch, I’ve carefully used a brass punch and tapped them back out.
You use the nut and bolt that went through there to push that bushing out. You'll slide the bolt through on the opposite side and put the nut on the bolt flange OUT and then you hit the head of the bolt. It works perfectly everytime. It will stop on its own because the flange of the nut is larger than the hole the bushing lives in so it knocks it flush. Plenty of space to get whatever in and out.
Then you just install the bolt like normal and as you tighten it, the bushing will be pulled in to its normal position
FYI the part circled isn't a bushing per se, it's a sliding sleeve. it's a press fit into the control arm. You put the shock in, tighten the bolt/nut, that slides to take up any slop so you have direct metal/metal contact.
As CR-Rex stated, you will have to push them back out when installing new suspension. Typically a bolt, nut, socket and a few minutes will push it back out enough to put in the new suspension. Don't try and hammer or pry on it, bolt/nut method works very quickly and easily with no damage to anything.
