    Hi All,

    I needed to replace the top mount on a Mitsubishi Lancer and hey presto the top of the strut has a section with two flats which needs to be held stationary while the nut below is rotated.

    So, below a solution .... a homebrew version of the manufacturer special tools...

    [​IMG]

    I milled two flats on the 17mm 1/2 inch drive deep socket to take a conveniently sized 25/32 inch wrench... The socket was horribly tough to mill even with an inserted carbide cutter (especially as I'm new to milling work). The narrowest portion of the socket was bored out on the lathe to pass a 3/8 inch socket extension.

    Then starting with a piece of 16mm round steel (EN24T as far as I know), I milled out a 3/8 inch square recess on one end and the necessary flat sided recess to fit the strut on the other end.

    And this is how it fits in use...

    For reference and for anyone searching, , the Mitsubishi special tool is part number MB991680 comprised of MB991681 and MB991682.

    The top mount is now changed incidentally. And there was much rejoicing.

    I use a cranked ring spanner and an open ender or a deep socket and the rattle gun.

    Nice solution. I had the same issue on a polo a few years ago and chopped a socket in half and welded it to a bar with a hole through it.

    Then when faced with the same issue but different size socket on the next car I splashed out on a Vortex (pass through) socket set and have used it only a couple of time but it’s worth it’s cost. One of the few tools I would loan if anyone ever needed it for that exact job.

    Welded sockets to angle grinder keys before for other types with the Allen key centre.

    Usually now a decent nut gun will blip the nut off easy enough without holding the strut.

    After years struggling to undo them the correct way using hand tools I came across a strut so tight it wouldn't budge. Discovered the grips & windy gun method, now I use nothing else! ;)

    How does the windy gun socket combination get on if the mole grips are on the two flats at the top in the way?

    I think they are holding the shock shaft instead with molegrips

    As above, cranked ring spanner and an open ender/adjustable to hold it. Buzz gun off once it's free..

    I did some struts years ago & nothing would hold on the chrome shaft enough to allow it to undo. Strut was scrap anyway, so out with the arc welder, large splodge of weld through the spring with welder turned up to burn through the chrome. This allowed a pair of stilsons to grip the shaft, worked a treat.

    Don't usually need the grips - usually enough resistance to the shaft rotating for the gun to spin the nut off.

    If there isn't, shove the bump stop down and grip the very top of the shaft under the top mount - the bit that won't be sliding past seals due to the bump stop, so it doesn't matter if you damage it slightly.

    Windy gun normally does it for me.Thats not to detract from the cracking job @jgr2015 has made of that proper tool, at least he gets to torque up the nut instead of just guesstimating the gaddagars

    It's good to hear the collective wisdom of this site as always.

    I reckon I've just about time to get an email to Santa for a decent windy gun.

    And on that note Happy Christmas to one and all !
