knocking wishbone bolt-oval subframe!

[paultownsend]

so i have had a knocking for a while. turns out its the wishbone bolt that goes through the rear bush/subframe.
i picked up, and torqued up new bolts from VW. still knocking. took them off for another look and the subframe hole looks ever so slightly ovaled. what options do i have?

new bolt obviously, but would i be better using a high tensile steel bolt and put some mega torque on it?
i tried torqing up the old vw bolt (stretch bolt) but it just went soft.

could i try fit a new bolt then spot weld to subframe?

Probably better to weld a washer to the subframe wouldn't it? Stacey had this issue and he built up the area with weld and then ground it back but a big penny washer welded to the subframe would work too I'd guess?

Found it. Mine looks perfect compared to that!
Thinking it must be something else

Replace the front bolts too mate. I went trough this recently and new front bolts sorted it!

i fixed it! i fitted poly ARB drop link bushes a while a go and basically they are crap. also the bolts were seized, and i may have done them up too tight! all greased up and all new stretch bolts. again! back to the OE drop links me thinks!
