Swifty oh no Posted May 11, 2010 Share Posted May 11, 2010 I have a SII74 lightweight and am changing the rear springs at the same time as fitting anew rear crossmember. I have tried loads of imperial sockets on the rear axle "U" bolt nuts but cannot get anything I have to fit properly. Can somebody tell me what size socket I need for this please?

Swifty oh no Posted May 11, 2010 Author Share Posted May 11, 2010 That's SIII 74 not SII Quote Link to comment Share on other sites More sharing options...
errol209 Posted May 11, 2010 Share Posted May 11, 2010 That's SIII 74 not SII They're M12 or 7/16"BSF - an 18mm spanner/socket fits this, or 19mm for the M12. Quote Link to comment Share on other sites More sharing options...

samtope Posted May 12, 2010 Share Posted May 12, 2010 I used an angle grinder and cut through the U bolts. If you dont plan to use them again, and everything is well supported, why not? They do come apart with a snap though! Quote Link to comment Share on other sites More sharing options...
samtope Posted May 12, 2010 Share Posted May 12, 2010 Unless you're looking for sizes for the new parts, in which case disregard my post above! Quote Link to comment Share on other sites More sharing options...
Swifty oh no Posted May 13, 2010 Author Share Posted May 13, 2010 Yeah a grinder was an option but I like a challenge so loads of WD 40 over the pst week and a new 18mm socket, all off now although one of the legs of one of the U bolts did shear as soon as I put any pressure on the nut to undo it. I will be replacing the U bolts and all of the shackle bolts etc. Out of interest I am assuming all bolts etc are as a standard SIII, hope so that is what I have ordered? (not springs, I have used, v. good nick ones from a lightweight after someone changed to parrots rubbish. Quote Link to comment Share on other sites More sharing options...
