My genuine LR sidestep top flat extruded aluminium section has come detached from one of the box section steel mounting tubes.
There are pop rivets through the bottom of the aluminium section and into the steel tube.
The plastic twin mats are clipped to the extrusion and must be detached to reach the pop rivets to drill out and replace.
.
There must be an easy way to remove the mat from the extrusion, does anybody know how is best?
.
Kind regards from Fred

It's a good guide, but not sure it will cover exactly what you are trying to do....do they not just prise off? Foraging near Gaydon....

Hi Fred. I wiped my passenger step off on a stone wall. All the rivets sheared but the mountings survived apart from a slight bend in the front one. Tried to get the rubber off to repair and re-install the same as you are attempting. Failed.

Gave up in the end and botched it - drilled right through the rubber / step / support arm - and fitted three through bolts with nuts. Filled in the rubber penetration holes with black mastic. Feels just as sturdy as the original and who is to know. Apart from you of course! Now - Black 2012 FR2 SD4 XS really miss the RRS

Swmbo managed to knock off my n/s step on a high curb. It sheared the actual step off the three metal prongs that go under the car.
It was fairly straight forward to fix.
You'll need some tigerseal and some 2" (ish) bolts that can self tap through the hole left where the rivets went into the step (the step is aluminium).
Take the prongs off the car and drill all the way through where the rivet used to be so now the prongs should be able to allow your bolt to pass through. Clean up on the underside of the step and apply the tigerseal. Then place the prong back where it used to be before it got knocked off and do the bolt up. This should hold it all nice and tight.
Do all three prongs this way and slide the step back on to the car 'adjusting' the prongs with small hammer until it all slides in nicely. Nip up the bolts and hey presto. All fixed.

You can't re rivet it as you cannot get into the inside of the step to do it

I thought about doing that but as I am 15 stone, sometimes 'take a drink', and then use the step as a passenger.
There is very little meat on the snot aluminium steps and I doubt if self tappers and glue would take my tottering weight. That is why I went the other way and put a through bolt via the 'prongs' as you call them.
Did anyone notice how I said the problem would be my weight on the bodjed passenger step and never mentioned my better half  Now - Black 2012 FR2 SD4 XS really miss the RRS

I can assure you that the original Steps can easily take nearly 18 stone of weight without an issue. Aftermarket ones may be as much use as a chocolate teapot, but mine are solid as a rock!! Foraging near Gaydon....

You'll trust six little rivets but nut chunky bolts and tiger seal (that literallyanything to anything forever... )
The forces on the step are all applied downwards on to the prongs. If they were going to encounter greater lateral forces etc then maybe I'd consider different options.
It's been months since the fix and had no issues with them being used by people heavier then 15 stone
