Arjan Posted April 12, 2022 Share Posted April 12, 2022 I hope to take delivery later this year of a new rear axle casing and would like to keep it for a long time. - Do I have the tub galvanized or not ? - Do I have the tub powder coated or not ? What are you experiences / views on this please ? Quote Link to comment Share on other sites More sharing options...
Mossberg Posted April 12, 2022 Share Posted April 12, 2022 I thought of galvanising but was worried that the sealing faces may end up with an uneven coating on it. Galvanising can be a bit of a lottery with the quality of finish. I am not sure it will be an issue or not. You will also have to retap the holes and certainly the diff case studs if you are leaving those on. For the cost of galvanising I think it would be worth it if it wasn't for the points noted above. I think painting it with good quality paint and then coating with a good corrosion inhibitor should be viable - but I think reapplying the inhibitor on a regular basis is important. I have actually considered a putting ends in the bump stop plates and filling it with grease. The shock and spring mounts will definitely getting a good coating!

Maverik Posted April 12, 2022 Share Posted April 12, 2022 I've galvanised 3 front ones I think now, do it, either cover the threaded bits or put old bolts/nuts in on holes to protect the threads. 2 Quote Link to comment Share on other sites More sharing options...
miketomcat Posted April 13, 2022 Share Posted April 13, 2022 Don't powder coat. Poor powder coat comes off in sheets and the only way to know it's poor powder coating is when it comes off in sheets. Mike 2 1 Quote Link to comment Share on other sites More sharing options...

I wouldnt powdercoat ANYTHING, except maybe alloy wheels, but even that can be problematic Galvanise, then Mordant, etch prime and the paint of your choice.

defender dinky Posted April 13, 2022 Share Posted April 13, 2022 Powercoared a chassis never again, after few month looked a right mess chips easy come off in sheets, and it's very hard to patch up after, dd Quote Link to comment Share on other sites More sharing options...
JeffR Posted April 13, 2022 Share Posted April 13, 2022 Avoid powder coat. I had a bulkhead powder coated, now its rotting underneath, powder coat is nigh on impossible to paint over when it chips. Bloody difficult to remove too Quote Link to comment Share on other sites More sharing options...
landroversforever Posted April 13, 2022 Share Posted April 13, 2022 The big problem with powder coating, particularly in the UK is the total lack of quality from most places. Not prepped properly for it to stick and most of the time not primed properly either. Blast it properly, zinc prime and it will be fine. That said, I'm going to be galving my cases when I'm done with them. Quote Link to comment Share on other sites More sharing options...
Snagger Posted April 13, 2022 Share Posted April 13, 2022 If you are worried about distortion, uneven coating of the flanges and coating threads, why not have it hot sphincter sprayed? 3 Quote Link to comment Share on other sites More sharing options...

Mossberg Posted April 13, 2022 Share Posted April 13, 2022 Interesting to know people have had the cases galvanised before. We're they difficult to clean the threads after? I am a big believer in galvanising where it can be done without creating problems. If I hadn't just painted my axle casing i would be having it to the galvanisers to work their magic!!

landroversforever Posted April 13, 2022 Share Posted April 13, 2022 Not an axle casing, but cleaned up plenty of threads post galv. Never had any issues as long as you’re careful with getting the tap started for clearing the thread. Quote Link to comment Share on other sites More sharing options...

A good coat on the discs as they are always going rusty - can't understand why no-one has thought of that before! Quote Link to comment Share on other sites More sharing options...

Is there anything you'd like to admit to the forum? *May not be true. 1 Quote Link to comment Share on other sites More sharing options...
