It does cunk on that side yea!Sounds like bushes to me. Does it clunk when suspension is moving up & down or when you take up drive?
I ended up using an assortment of spanners behind a nut and washer to drive it half out and then a slide hammer to finish it off. Took about 5 mins and no damage to spindle.If they are the originals in the arm, they are metal cased and need pressing out. I have a pin removal tool to get the pins out otherwise they are pigs to move and you will usually end up wrecking them getting them out if you use a hammer & drift. I would order some new one to be safe if you decide to do them.
You will also need to change the inner bushes at the same time. One word of warning from someone with bitter experience, is remember to use plenty of polybush grease before you fit new otherwise, like mine, they will squeal!!
Thanks Farmer.If it clunks at the point where you have circled in red, then it can only be bushes or a worn spindle pin. Get a pry bar between the control arm and the cotter pin and test where the movement is. It could be a worn control arm housing that is not holding the bush properly. If so, I have a spare control arm if you want it. You might also want to check the inner bushes at the other end of the arm.
If there is no movement or it doesn't clunk there, it could be the anti roll bar tie rod & bushes (the bolt with the red bit at the end on your pic). That looks quite new though. There could be other areas that could clunk but that would be on take up of drive e.g. driveshaft, hub bearings, propshaft UJ, etc.
I have replaced several of these bushes with urethane bushes so here's my thoughts. Firstly, the bush kit I use are an extremely tight fit. you have to clamp them together in a vice to get them in the control arms. Once they are fully home it is then very difficult to get the arm over the strut as there doesn't appear to be enough room. Do not be tempted to shave a little from the end of one of the bushes. It is designed to be a very tight fit as tightening up the pin nuts does not clamp the inner bushes. these get compressed when you force the arm onto the strut. The only way I've found to do this is by making a small chamfer on the leading edge of the bush to get it started. Remember lots of grease on the moving surfaces. I'm not sure of the fit of your bush kit. Did you have to remove the metal sleeve from the old bush?
