Hi all. 
 

so I’ve recently done a job I’ve done a dozen times on different cars and that’s rebuild front suspension. 
 

I’ve dropped the subframe, painted it and replaced the lot. Shocks, springs, wishbones, shock mounts(including bearings) anti roll bar bushes and drop links. 
 

I also replaced the steering rack as it was leaking (that’s what instigated it all) only thing I haven’t replaced was track rod ends. 
 

it all went out and in fine except I have this odd crunching noise on the passengers side. 
 

it only happens when the suspensions fully contracts or extends. Up and down speed bumps is the main occurrence. 
 

Any other road surface is fine, even very rough surfaces. It seems to be so long as it doesn’t fully extend its fine. 
 

I’ve gone round everything and re-checked all things I’ve touched, including removing those pretend strut braces to check top nut and it all looks fine. All my alignment marks haven’t moved. 
 

Just wondering if anyone has any advice or recommendations on how to tackle such an issue. 
 

it’s unfortunate I’ve replaced so much in one go as it means allot more could be causing it I suppose. 
 

thanks. 

I would definitely have changed the Track Rod Ends so start there

Is everything tightened correctly? Especially the front frame?

Could be CVs though especially if you let them hang with the hubs/brakes attached whilst the frame was out

Yea you’re probably right. They are the oldest thing up there now.  

I’ve checked them by hand and there no play but then I’m sure the car is a little rougher on them then I can be!

everything was torqued down according to the specs given in my Haynes so assuming that’s reliable (and my wrench isn’t out) it should be tightened down fine. I tippex marks on everything (when I first started on cars had a wishbone come loose in an old Megane so leant my lesson there) and none of them have moved. 
 

nope everything was tied up including hubs and axels. Didn’t let anything hang on it’s own weight. 
 

can subframe bushes cause such a noise? First time dropping a subframe (i used alignment pins on the way back up) so not sure what kind of noises they can make when aging.
