REAR DOOR FAILURE

[ricster]

I didn't realize the weight difference was as much as 10kg.

Wear on the hinges makes sense though.... thanks for the info!!!

I think that the "bending force" / i.e. load on this specific area which causes this kind of crack / metal fatigue mainly occurs during the closing process of the door. When the door is closed there should be very little force on this areas as everything is locked and held in place.

This bending force during the closing process will be even bigger if the door is sagging / not properly aligned.
If the door is misaligned you have virtually a double impact.

The more you open and close the right hand side the more wear on the hinges.
You could also say that the increased weight of a bigger tyre will have an effect on the wear of the hinges.

So.. I think it is important that the alignment of all components of the barn-door assembly is as good as possible in the first place to avoid premature fatigue failure.
At the bottom of your RH barn-door you have a horizontal striker (round bolt) .
This striker slips into a tapered guide mounted on the vehicle side.
Make sure that both components are aligned perfectly.

This is quite possible, but I have a feeling the damage was done in the time before I had the vehicle. It was serviced by Graham a couple of times before I bought it and on one of the job lists I saw he had his hands on the rear door. So it probably was not so lekker, which he then sorted. Perhaps the metal was almost at cracking point and the increased weight and force of closing the door, it just couldn't handle it anymore, I don't now . Either way it's busted and needs a fix!

Peter is right, I recall my disbelief in the weight difference when loading and unloading the old and new tires. The 285's are moerova heavy!

Good day Picasso!
I saw your post and fix of the rear barn door and was very impressed. I have the same problem and will have to go your route.
Can you tell me please, since this job is at least 20 months old: how well is the job holding up?
Thanks and regards from Windhoek!

Hallo Andreas

There is absolutely nothing to report in terms of deterioration.
Its solid like a rock (well steel).

I don't think welding would have lasted the same way.

Take your time and prepare well beforehand.
Have a second set of hands ready when it comes to the bonding process.

Good luck with your repair.

Thanks Picasso, firstly for the fast reply and secondly for the POSITIVE news!

Moving the spare to the roof for now. Hope I dont get a flat because I might bust my back time to ask SWAMBO for that rear replacement bumper Haha

[hugejp]

That is a kek one man.

You'll need to get that repaired, but for now you may want to drill a small hole at the end of the crack to stop it running any further.

That's a good idea I'l do that thanks I guess if there are any positives with this it's that I managed to follow the examples in this thread and I re-alighned the door so that I dont have to slam it anymore. Also cleaned out most of the dust and repaired the seal between the panel and the inside of the door. Should be alot cleaner inside now for the next few trips...

Once again the forum comes to the rescue
