    Front Suspension Help Request

    Only partial success today replacing shocks and springs.

    One side stopped me in my tracks when I couldn't remove the top shock nut. Managed the other side with the T45, which considering the general level of corrosion on this car was probably a result.



    So my question is can I get away with a cheap shock clamp like the Laser 5791?



    Or will it take the four bolt Smart clamp to do the job?



    If so, does anyone have one they are willing to lend to me? In return I will make a small donation to your favourite charity.

    One thing that did help was the Clarke CEW1000 Electric Impact wrench, wouldn't have been able to budge the second shock nut otherwise.

    Wait for it!!!

    Tolsen's going to be on this one like a rat up a drainpipe showing you how to do it with a couple of bits of wood a G clamp (from Lidl of course) complete with mathematical calculations!

    A garage wouldn't piss about with the clamps as you're replacing springs and dampers they would resort to a slitting disc in an angle grinder and cutting the spring first and probably the top nut - just changed the front shocks on a car this week with the the evidence of that method clearly visible in the form of slits in the top retaining cup!

    Personally, I use the proper clamp - and it's seen some service!

    Hadn't considered that.

    But mainly because although I could see the nut splitting, slitting the top of the shock piston would be much more interesting.

    I tried using my fairly heavy duty Craftsman (Sears) mole grips to hold the shaft, but they failed and didn't even mark it - that's how hard it is.

    My local garage admitted to me recently what they did in your situation - and didn't damage the top cup.

    Again, this car was having new springs and shocks - spring cut off with angle grinder, concertina cover pulled up and held while a metal bar was welded to the shocker plunger rod followed by impact wrench on top nut.

    There is also the possibility of grinding some flats low down on the sides of the pushrod and putting a spanner across to hold it.

    I was with you until then, because I was trying to work out if there was anyway to get my impact wrench to the top nut.

    There isn't - no line of sight, and no possibility of using a wobble bar.

    Ok so have you tried any heat and a breaker bar on a socket?

    This method of applying heat worked for me in the situaion illutrated!

    It should generate an amicable atmosphere.

    You could alternate between that and some soft music.

    I'll get me coat.

    Top of shock needs a 7 mm Allen socket, not a T45. I normally fit a second nut for strengthening when cracking loose stubborn top nuts. Have not been defeated so far. Got a proper Smart strut clamp as back up but have never needed to use it in earnest.

    I think the main problem is you have never invested in quality tools. I counter hold shock spindle with a 7 mm Allen socket and turn nut with a Lidl deep reach ring spanner.
