hi all,please help!!! i have a 69 mk2 mini,i have fitted a lightweight rear subframe,which is basically a bar which bolts to existing subframe mounts and holds the swinging arms, i have fitted gaz coil over shocks to this set up with 7x13 minilites. the problem is the drivers side only,when i hit a bump but not all bumps i get a severe knocking noise from the subframe/coilovers. this doesnt happen on all bumps,it seems it only happens on bumps that as well as forcing the wheel up into the arch,also pushes the wheel slightly left or right,head on bumps it works fine and quietly. i have checked all bolts etc and everything is tight wih no play in any bushes,bearings.
could this possibly be a worn radius arm pin? could it possibly be the spring fully closing and knocking on itself?. i have adjusted the height to ensure its not hitting on arch. it doesnt ever seem to happen on the passenger side rear wheel. any info or ideas will be greatly recieved,many thanks,sam
p.s i run my tyre pressures at 40 psi,is this the correct pressure for 175/50/13`s?
