Anyone Galvanized Swivel Housings?

Last year i replaced my drivers side swivel ball, and this year looks like I need to do the other one.
I also have some upgrade vented disks and calipers to fit so I was thinking of doing it all together.
looking at the swivel housings they are pretty scabby and I would like to sort them out while they are off, I was going to clean them and put on some paint but how long will they stay good.
Just wondered if anyone has tried Galvanizing the housings? I was thinking of getting the tow bar bracket done and might even get some brake shields and send them too, so I wondered about getting all the bits together and have them done
 
I don't know how long the galvanizing would stick to the swivel housing. But once it starts peeling the seal will get damaged and leak, but i'd be interested to know how long the galvanizing would last :confused:

Maybe I didn't get the description clear here, I was thinking of Galvanizing the housing which is prety rusty ( see picture ) not the swivel ball itself, I know it would need the bearing housings cleaning out top and bottom, to fit the new outer races, may even risk putting some better bolts in too, but just wondering if anyone had tried it

i see what you mean, they aren't the sort of thing that particularly need that sort of attention, i painted mine and they have been fine so far.

I've never had to do anything on the swivels on mine apart from top up the grease. I would guess there is a mating face on the housing to ball. Given that I would say galvanising would not be suitable for that part. Only an opinion and could be wrong.
 
Paint is probably going to work out to be cheaper and longer lasting if done well

I wire brush the heck out of these parts (with angle grinder) soak them in rust eating solution (such as Rustyco) and then paint them with a decent anti-rust primer (such as Ferpox) and then go over the top with a decent chassis paint (such as Eastwoods extreme chassis black / KBS Blacktop)
 
Would be a very long lasting and durable finish. There is a risk of distortion during the hot dipping, also any threaded holes would need cleaning out with a tap after galvanising. Zinc would also need to be removed from any bearing surfaces / seatings (never taken one apart so don't know if this is applicable). And any sharp whiskers will need to be fettled. Normal to shot blast to SA2.5 before dipping, this might damage bearing surfaces.

Yes that seems to cover the concerns I had, not worried about tapping the holes, but the top and bottom swivel bearing bores may get coated and be a pain, and I'm not sure how the lump of a housing would take to the sudden heat on the surface.

That was my first plan and may possibly be the best one, but I need to get some other bits Galvanized and it just crossed my mind, I thought I had seen some pictures of the housings galvanized somewhere, but I looked and cant find them, so I wondered if anyone might have tried it before and could tell me if its OK or steer well clear.
 
Thorough degrease, clean, prime and paint, I would think those would last 20 years at least.
Galvanising usually lets go after about 25 if exposed to atmosphere.

I have never had any castings that were galvanised, it is usually on mild steel. Never seen that done in 35 years around landies, far as I can remember.
 
Yes I had a lot of stuff galvanised, including the axle casings them selves done, I didn't actually have the swivel housings done, it was something I debated long and hard and in the end decided it was a step to far and ended up with paint.
Paint I used a Corroless primer (supposedly the dogs bollocks) Over that any generic top coat, depending if you want matt/gloss finish.

But back to the galv question, S884 on here had his done, and having spoke to him he said it was a bit of a nitemare and took ages to clean them out, but I suppose if you have the time to dedicate to it then it isn't an issue :)

Cheers Arron that is what I was wondering about, I need to get some parts done and I just wondered if anyone had tried it before, probably saved me a load of messing about. I will get the needle gun and wire brush on them and then coat them with primer and some black top coating. already done my "new" brake calipers with enamel, just working up the energy to get started on the next phase.
By the way looking forward to seeing your next update.

There is no need to use hot dip galv.

We have used cold galvanising for many years with no ill effects.

Try Galvafroid, which is the one we use ... http://www.tools-paint.com/galvafroid-zinc-rich-cold-galvanising-coating-800ml-2218-p.asp

That is a name I have seen used on structural steel work.
Its confusing the different paints available looking at the different products you can find so many miracle cures at all different prices, some say apply direct and others need a primer, I may use this one and see how it goes.
