John Bonnett Posted March 14, 2016 Share Posted March 14, 2016 I'm making the change to M12 wheel studs and intend to follow the well trodden route of doing the rear ones in situ. My concern is that they will be very tight and I'm afraid of damaging the hub flange when I remove them with a heavy hammer. I was planning to get a weight behind but would appreciate any advice please.Thank youJohn Quote Link to comment Share on other sites More sharing options...
spittyholly Posted March 14, 2016 Share Posted March 14, 2016 i just bashed mine out they wasnt that tight maybe put the nut on the end so as not to swell stud when hitting but mine came out easy Quote Link to comment Share on other sites More sharing options...
Nick Jones Posted March 14, 2016 Share Posted March 14, 2016 They usually knock out pretty easily, without undue violence. Couple of solid clouts or a few more lighter ones. Getting them back in can be more challenging.One thing you will likely find seeing as you have rotoflex with a fat bearing housing right behind the rear wheel flange is that also you can just wriggle the standard studs in and out, anything bigger causes problems. On mine, when fitting the M12 Freelander studs (which fit nicely), I had to drill a hole in the brake backplate to feed them through. Irritating but not a complete disaster.Nick Quote Link to comment Share on other sites More sharing options...

Can that be done from the front by rotating the flange to a suitable position? Quote Link to comment Share on other sites More sharing options...
Nick Jones Posted March 14, 2016 Share Posted March 14, 2016 I think I drilled mine from behind. It wasn't much fun......NickEnd result.... of a 13mm drill and some filing Quote Link to comment Share on other sites More sharing options...
MarkB Posted March 14, 2016 Share Posted March 14, 2016 I recently replace the standard studs with M12 on my Mk2 GT6, and I found it easy just to pull the hubs off in situ knock out the studs and replace on the bench. That way you can belt the studs fully home on a vice and not rely on pulling them through with a wheel nut. Possible but awkward to drill the backplates on a rotoflex set-up, not a lot of room.Mark Quote Link to comment Share on other sites More sharing options...
GT6 M Posted March 15, 2016 Share Posted March 15, 2016 John, ye,ll need new nuts too, so suggest that thee,s are consideredvv light, strong, and rust proof,unlike alot of othershttp://www.ebay.co.uk/itm/TITA.....d:g:e7EAAOSw9mFWLftn5 diff colours too.http://www.ebay.co.uk/sch/i.ht.....p;_skc=600&rt=ncM Quote Link to comment Share on other sites More sharing options...

CHRIS211083 Posted March 16, 2016 Share Posted March 16, 2016 I didn't need to drill the hole in the backing plate for my rear studs. Try moving the flange round till they slip in. Just fiddly.Chris. Quote Link to comment Share on other sites More sharing options...

I posted mine off to them on Monday and the replacements arrived today. What fantastic service. Quote Link to comment Share on other sites More sharing options...

Nick Jones Posted March 16, 2016 Share Posted March 16, 2016 There's more room on the swing axle cars. The roto bearing housing is bigger and gets in the way.NIck Quote Link to comment Share on other sites More sharing options...

byakk0 Posted March 17, 2016 Share Posted March 17, 2016 I've been told to freeze the new studs to shrink the metal slightly so they slip in easier. Haven't gotten to that part yet, if and/or when I upgrade to the land rover studs in my possession. Quote Link to comment Share on other sites More sharing options...
