I'm replacing my factory struts with the KYB's, got the GM10 tool, but the strut retaining nut, the one you need the 4 prong tool for, does not seem to seat all the into the stut housing. If I thread it in without the strut it seats all the way. It appears the top of the strut of the KYB's interfers with it going in all the way. Is this right, quick answer would be nice. Thanks...T :dunno: :confused:
