Undoing The Locking Nuts On Suspension Tops.


Recommended Posts

Hey guys,

Bought some standard shocks for my 33 gtr, only need the tops off them (couldn't give a stuff about springs/shocks) but for the life of me can't get the nuts undone at the top of the shocks (the ones on the massive thread). Don't want to strip the nuts so does anyone know of any tricks. If all else fails i'll cut the springs to release the pressure on them.

Tried wd40 and such, the nuts slightly turn, but then I realised it's the internal bit of the shock turning with them.

Any tips?

Cheers,

Ash

get a nice big breaker bar on it and then give sudden pulls on the bar, don't just gently apply pressure as they will turn the whole thing. if you are jerky in your movement you will have more chance in 'cracking' it and getting it undone.

Coil compressors wouldnt be better than cutting the springs as a last resort? :D lol

Yeah tried that too lol. The stock springs are too long for the compressors I have, so did them a bit down at either end and couldn't get enough force on it to relieve the tops. The springs are pretty crappy though anyway so no big loss if they must be destroyed :)

hehhe, good luck with that.

I ened up having to hacksaw it off (very very carefully so as not to saw the thread on the top of coilovers).

Breaker bar and the best socket available so you dont round the nuts off and wind up where i was...

Umm, sorry to ask the obvious but you're holding the top of the strut still (above the nut) whilst trying to undo the nut yeah? Like this (from the coilovers thread):

One of my front struts had the top bit cracked so I ended up sawing the strut in half to get the spring out, lol. Had I only had a pair of locking pliers...

I then put the remaining top half in a vice and finally got the top nut off, just in case I need the strut top for something else later on.

Yeah that's the bit mate. Can't find anything grippy enough to hold onto the tiny flat bit at the top of the thread. The whole strut (inner bit) just turns when I undo the nut.

Will give the breaker bar a go, however if that fails then will break out the grinder!

So you're trying to take the top nut off without compressing the springs?

Yes, my compressors are about a coil too short for the standard springs. It wouldn't be worth me buying longer ones, since I couldn't care less about spring integrity and have a grinder on hand.

Just compress the middle coils, that should give you enough slack to get the top nut off. I used something similar to the SuperCheap tool and it worked fine on R34 GTT stock springs.

Rattle gun will whip these nuts off.

Some shocks have a D shaped shaft where it passes through the spring perch, which gives you something to stop it rotating. Others have an internal hex which lets you use an allen key (with a ring spanner). Best method tho is a rattle gun. Even if you don't own one, take it to your favourite suspension place and they'll ususally undo the nuts for you for a small fee (probably zero if you ask them nicely, or actuaually ever buy stuff from them). They will also have the spring compression stuff to do it all safely.

Another way to compress the springs is to undo the nut while the struts are still in the car. Then jack it up and remove the whole lot (there are several ways of compressing / jaciking off a stub axle etc to make it easier depending on how hard it is to get the strut out, but that's too much to type coz I'm a lazy bastard)

+1 taking it too your nearest suspension shop, rattle gun take 10 seconds- you shouldn't take the nut off without compressing the springs in case the stored spring energy which is now suddenly released imbeds the strut top into your skull.

Compress the spring as much as you can. Put an open end spanner on the nut then get a shifter and grab the top EXACTLY like V28VX37 has given a pic of above. The wrench can be locked from turning on one of the 3 screws.

this will work. BTW, these should come off very easily, they are only to be tightened to 20Nm or some such, not compressed the entire way down the shaft and locked at the end of the thread.

    • Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!
    • To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules
    • So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket
    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
