Creak­ing bush

Car Mechanics (UK) - - Help! -

There has been a re­ally an­noy­ing creak com­ing from the front sus­pen­sion of my 2002 Vaux­hall As­tra Mk4 Ber­tone 1.8 since I bought it. It’s es­pe­cially loud over speed bumps. I fi­nally traced the creak to the front near­side anti-roll bar bush, so pur­chased a re­place­ment, as­sum­ing it would be a sim­ple fix. How­ever, the rear clamp bolt go­ing into the sub­frame is very dif­fi­cult to ac­cess due to the bulk­head/ chas­sis be­ing in the way. I was told it could be reached with a 10mm flexi-head span­ner, but it’s still very awk­ward. I couldn’t get a good grip as it’s an E12 Torx bolt and not hexag­o­nal, so rather than round off an al­ready dif­fi­cult-to-ac­cess bolt, I left it.

I can’t find an E12 Torx flexi-head span­ner any­where. They all seem to be the reg­u­lar Hex style. You could prob­a­bly fab­ri­cate a tool to ac­cess it, but lack of a welder makes this dif­fi­cult. If you have any ad­vice on how to ac­cess and re­place the bush with­out drop­ping the whole sub­frame, I would be very grate­ful. Paul Mc­cully

You can buy a five-piece Torx flexi-head span­ner set for £29.99 in­clud­ing de­liv­ery at this link https://amzn.to/2ngvbsi. This set in­cludes the E12 span­ner you re­quire.

I haven’t used one of these my­self and have nor­mally been able to com­plete the job by loos­en­ing the bolt ini­tially with a stan­dard flat E12 Torx span­ner, then un­do­ing it us­ing a ¼in­drive ratchet with a six-sided 10mm socket. Soak­ing the bolts for a while with pen­e­trat­ing oil should help to ease re­moval.
