Frankia rear wheel arches

My 10year old Frankia’s wheel arches are getting brittle and cracking

I think its time to change them


Anyone else had to do this ?


Wondering if I should attempt to make some out of fibreglass or try and get new ones from Frankia

If you have any experience of GRP I'd say make some new ones.
They don't need a cosmetic finish so mould template can be simple, you could adapt what is currently there so long as they are sound enough.

Materials are relatively cheap and your time /labour will be free, so a big cost saving over trying to get them from Frankia, that's if they still supply them?

Must say though when I had a Frankia and wanted parts they supplied direct from factory and were very efficient.

Could you not stick something over the top to make good/sound.

Hi Coppo

I have been using sikaflex sealant over each crack as i and when i notice them and this over quite a few years

These have all been around the flanges where they connect to the floor and on the side of the arch at the inside of the outer wall

So i could carry on doing this and actually will have to do this tomorrow to make a temporary ( possibly permanent) repair otherwise i wont be able to use the camper
coppo and coppo like this.

Sealing the cracks is definitely better than doing nothing.

Sounds as though a permanent solution needed though.
If the originals lasted 10 years presumably new replacements should do the same.
Or you could make some GRP ones and they will outlast the rest of the van.

Personal Aire
Would it be easier using aluminium? I'm thinking tin-snips and riveter.

I'm not signing anything.

The two impulses in travel are to get away from home, and the other is to pursue something - a landscape, people, an exotic place. Certainly finding a place that you like or discovering something unusual is a very sustaining thing in travel.

Temporary repair done today using 100mm rectangular flat air duct cut up to give me a right angle and fitted in sections to follow the semicircular arch with copious amounts of sikaflex

Spacerunners suggestion got me thinking

As I needed something to come down the inner wall and wrap under the arch cut out , the aluminium that i had was too thick for me to bend Thats when I came up with the plastic air vent ducting I cut it in half so it was L shaped instead of rectangular then cut to fit the curve

Rather pleased with the result , will check the other side in the weeks to come
