Carrying on the theme of useful musings after my bit about jacks and axle stands, it just went through my mind that how i dealt with changing that drop link might be of interest? or maybe not? if so apologies!

As I'd renewed struts, springs, top mounts, etc earlier in the year the top nut came away really easily as It had been undone and reassembled with copa slip at that time. The bottom nut was a completely different proposition. It was heavily corroded and even though I have been coating it with copa slip at each service it looked very "crusty". I find the bottom bolt is often the worse for wear due to being so exposed. I was able to get the Allen key into it's hole in the end of the bolt but there was no possibility it was going to stop the bolt rotating.

Faced with this situation I have two favourite default solutions. First off, the allen key is never going to work, so, give the threads a good wire brushing and soaking in your favourite release oil (I like Plus Gas best although my pal buys PB Blaster which I haven't yet tried. Must get round to that) Then I take my Footprint wrench and grip the narrow metal flange on the ball joint side of the antiroll bar. Socket on the nut and heave! The footprint (or similar design if you like) works much better in this sort of situation than the ubiquitous locking pliers (often generically named after a small burrowing animal which makes an awful mess of ornamental lawns) as it grips tighter the more you heave. You do need to be a little careful of the rubber boot if you are intending to reuse the link, but it's very doable.

If this doesn't work the quickest thing to do is just cut the nut and bolt end off flush with the anti roll bar using an angle grinder. It's very quick but only a solution if you are fitting a new link. If you have to save the link for reuse then before you start, using your angle grinder or even a hacksaw, cut off the threaded portion sticking out of the nut. You don't need it (why do they make that threaded bit so much longer than necessary?) and it's the corrosion on this bit which makes the nut jam up.

When fitting the new link the bolt needs to be held with an Allen key (or hex bit of some sort) to stop it rotating as the nut is tightened. Most of the after market links seem to use nylock nuts so the Allen key can be difficult to hold and a wee length of pipe is a help. as is a "go through" socket set. Here's my Vortex set in use. The ring end of a combination spanner works too but is much slower and once you own a "go through" (or "go thru" as the Yanks call them) set you will find lots of situations where they are useful - strut top mounts anyone?

Then it's on with the torque wrench. I like to torque all chassis and powertrain components.

And here it is all secure and looking good

especially with it's snazzy red star burst ends.

Hope Kenny appreciates it when he does the MOT in a couple of weeks time!
 
Hi Jock,

I couldn't agree more with your advice about cleaning the rust from the surplus thread sticking out beyond the nut you want to 'try' to remove.

Have you tried using your 'windy gun' (air wrench) on the nut and not bothering about trying to hold the stud with an allen key/hex bit?
This sometimes has worked for me (note the inclusion of the word sometimes :bang: ).

Re:- the use of 'go through' sockets, I note that Lidl stores here in Ireland will have sets of these for sale on Thurs 30 Jan. (@Euro 18.99). I don't know if the same product will be on sale in the U.K. on the same date - but in the past it has been., so might be worth watching out for.

Regards,

Al.

Hello Al, I loved reading your posts. As I've found with the opinions expressed by some others on this forum, we seem to have brains that think along the same lines.

Yes the gun works well on many occasions but in this instance, as it was just the one nut, it hardly seemed worth firing up the compressor!

Regarding the "go thru" sockets. I bought the Halfords advance "Vortex" set and they are very good. They look absolutely identical to the Draper sets but, with my Halfords trade card, cost me considerably less.

I first saw this type of socket in the US (SEARS I think it was) branded Gear Wrench. Nearly bought a set right there and then buy Mrs J talked me out of it as it would have used up all our baggage allowance! When I got back I made a mission out of finding out all about them.

From what I found on the internet The sockets used in the Halfords, Draper, Gear Wrench and Craftsman sets are all the same splined design. That is to say the top of the outside of the socket and the driving part of the ratchet fit together with splines. I think, from what I've found on the internet, they are actually manufactured by Apex tools? The Draper and Halfords sets look pretty much identical. The Craftsman and especially the Gear Wrench sets have superior looking ratchet handles and a whole range of extras (bits, handles, extensions, etc, etc) which you can buy as add ons which do not seem to be available from Draper or Halfords. I'd love the flexible head on the Gear Wrench handle when working down the side of engines etc. However I'm about 99% certain that the American branded items would work with the UK tools. Next time I'm over there (My sister lives near Boston) I'm taking one of the Halfords sockets and trying it out. Here's some useful videos on them:







There are other brands which use a hex coupling between the socket and ratchet:



I don't know so much about these but if I was considering buying again I would be looking closely at this type. Why? because the Draper/Halfords sets come with only a ratchet handle. That is to say they have no "T" handle/power bar equivalent. In fact I don't see any, Gear Wrench/Craftsman included, that have anything other than ratchet handles. This means that there is a slight risk of damaging the ratchet mechanism if you encounter a very tight fixing. I have to say the ratchet, which by the way has a nice fine tooth pitch so is good in tight corners, does seem very robust and so far I've not had any problems but if I had the set with the hex head then I could use a ring key with a length of pipe if it was really tight. One of the features of these sets that I like a lot is how little room it takes up in terms of depth compared to a "normal" socket and ratchet/powerbar/"T" handle. The Draper video shows this very clearly.

Hope you enjoy the videos and maybe they'll help someone.

Kindest regards
Jock
 
Hi Jock,

There's some lovely tools shown above, for some reason I always seem to be drawn towards cheaper versions of tools, providing I think they'll get the job done and give reasonable service (I'm not hard on tools :) ). But as you point out, sometimes spending more gets you items not available in cheaper sets plus better quality e.g. on the ratchet described.

The set I mentioned that might be in Lidl stores on 30 Jan. appears to use a hex on the outside of the sockets to drive them, it includes a ratchet, 11 sockets and a few extensions etc. The size of the ratchet/sockets seems to be what you'd find on a 3/8" sq .dr. set. The name on many Lidl tool sets is OWIM, Germany. This appears to be an import/logistics company not a tool manufacturer. (it might be also owned by Lidl?).

Regards,

Al.
