Sticky struts - where do I put the lube eh?

Post by Wooscary » Wed Sep 28, 2011 1:07 pm

I know this has been asked many times before, and I've searched for
a definitive answer, but where exactly do I lube to attempt to get a bit more life out of my front struts.

The nearside one is grumbling quite a lot.

Photographs would be great if anyone has any.

Thanks

Martin

The only way I have found succesfull on my TGD Auto is with an oil can pumpimg some LHM into the strutt return pipes every couple of months, my slightly higher mileage TZD has never had dry struts yet so I assume are self lubing/leaking?

You need to pull off the strut return hoses and plonk them in a jamjar full of LHM and do some citro-eaerobics!.

I'd start by setting the suspension at max height, taking the return hose assembly off the strut, feeding a thin hose through the connection hole of the strut as deep down as it goes and pulling the saltwater sauce away with an injection syringe or similar, and only then continue with the lhmrobatics.

It may be different in the UK, though - I suppose the roads are in better shape there (no frost bumps etc.) and the amount of salt they use on the highways during winter time is somewhat more sensible. Here, if the return hose happens to crack during the cold season (when the cracking usually occurs), it will not take long for the strut to be full of saltwater. And that's the root cause for sticking struts due to the suboptimal positioning of the return hose connection.

I think you wouldnt need to do worry about the salt too much, but a useful explanation though.

I think theres a few other posts in the technical forum about people who have done this, myself included and it made some improvement.

Thanks for the thoughts gents.

I've not worked on the suspension system at all, and without looking at the car (it's too cold and wet), is it obvious where the returns are, easy to remove etc?

They feed from the Strutt leg across to the inner wing, the pull of very easily from the inner wing (you only need to remove one)

I found it much easier with the wheels off, one at a time. The end of the rubber pipes were easier to get off that way (pulled off the end furthest from the struts).

So the wheel is off held on a jack/axle. Suspension is on low setting with engine on. Pull the end of rubber pipe from their fixing and plonk the open end into a cup/jar of LHM. Then put your suspension on high and as the car rises watch the green stufff being sucked up the rubber hose! When the cars at full height - refix the rubber hose.

The struts on my 16 Valve and TZi felt much better after I greased them up.
I put the car on maximum height setting a chocked up under the front subframe. Don't have to take the wheel off.
I then "popped" the bottom of the rubber strut boot up and compressed it all the way to the top with one hand.
You can then stick your finger up between the compressed rubber boot and strut to feel the "slider" at the top of the strut.
I cleaned this with a clean rag and then used a copious amount of grease to lube up the "slider".
Then slid the strut boot back down and popped it back into place.
Then proceeded to do some citroerobics (down, up, down, up etc..)

I've never tried the clean LHM trick.

I know it says replace the pipe with the strut full in the article but I think you are taking a risk with the octopus by blasting a full strutsworth of LHM through it when the car descends. Only very light returns are normally expected through this route. Better to exhaust the dirty stuff back into a jar before reconnecting the pipe.
