Since I'm replacing so many things in that area it seemed daft to spoil it holding all the new bits together it horrible old corroded screws.
I had a go at painting the lower arm with por-15 but TBH not satisfied with the results so have decided to bite the bullet and remove the bushes and get it powder coated and fit new bushes.
Another order for bits. The bill is climbing!!! :-(
Big parcel to collect from the post office! :-)
All seems to be in good order apart from a tiny bit of damage but that will repair easily. Needs a good clean though!
Superperformance order arrived. So now have 4 new lower arm flamblocs, new flamblocs and bushes for the ARB drop links. New flamblocs have flats on - not quite of their purpose???
Time to "burn" the bushes out which after watching a few youtube videos will hopefully be a lot easier than I imagine. Only a few tools needed.
TBH the bushes arn't that bad - main purpose of the job i to allow the arm to be powdercoated as even after a coat of por-15 it looked rank :-(
First one was the learning curve so didn't really take any pics bar this final one where a dropped a screwdriver into the hole so it could be knocked out. If I was doing the job again use the bolts from the inner bushes to drift it out. Basic process is you heat the meatal on the arm around the bush until the bush starts to melt on the inside which loosens the bush. YOU DON'T ACTUALLY TRY AND BURN THE BUSH!!!
When your doing it all the burnt burns away then after about 5 mins the rubber on the bush begins to squeeze out the sides a bit like toothpaste. If the bush did start to burn just take the heat away and then blow out the flames otherwise you will get acrid smoke like a burning tyre. The second one I did actually ushed itself out.
Here it is once out.
There's a bit of rubber residue left inside the arm which you can scrape out.
The washer on the end of the bush can be prised off after a bit of heat which helps - the first one I did ended up with the washer stuck inside the arm - grrr!!!
After washer is off.
Mid heat - you can see how all the paint bubbles up and if you look closely you can see the melted rubber oozing out the end - once this happens your nearly there but as I say it oly takes 5 - 10 minutes of heating.
Before extracting the bushes from the inner edge of the arm the forks need removing. I wasnt planning on doing this job so hadnt undone the bolts whilst still on the car so had to improvise a bit by standing on the arm to keep it still whilst undoing the nut.
At first you can only move the wrench a bit before having to repull it up but after a few goes it breaks off with a click
The nut n the other side started moving so had to put a spanner on the other side.
Pic from another angle with me out the way.
Once its loose you can tap it through with a lump hammer although the 2nd one didn't need that.
Repeated for the other side.
Quick pic of the bush for reference bd=efore I start - note all the bushes have the "washer" side on the inside.
Starting to heat it....
Bush starting to melt...
Final bush being melted - note the bubbling of the rubber - sounds like frying bacon but obviously not as tastey!
Everything apart - took about 45 mins in total max. Plan is to take the arm to the powder coaters in the morning and the brackets to either platers on Monday or have a go myself with my own kit.
You need to press out the steel sleve as well as the rubber in the bush is bonded to the sleve so you replace the bush as a whole
Oh goody! :-( Anyoe got any ideas on that one???
