Looking For Some Cracking Advice

Recommended Posts

Afternoon.

 

Bought this 2004 Lunar Quasar 615 in April.

 

There were 2 small cracks in the front panel, either side of the frame.

 

We've towed the caravan 5 times this year so far, and the cracks are getting worse. Tried repairing 1 but it split again as soon as we towed again.

 

Any advice would be greatly appreciated.

I think it needs to be looked by a specialist. Never seen cracks there before and caravan is 12 years old.

Have you crawled underneath to look at the A-frame??

 

That looks suspiciously like its flexing, possibly due to a fracture on one or both sides and hitting the front valance.

 

I have seen this before but many years ago now.

I have the same caravan with the same issue, i reinforced the inside with fibre glass sheets and resin then filled the outside with grp repair kit. The crack is inside the locker so no issue with water ingress, this is the weakest point and believe it may be caused with the stuff in the locker moving around.

The first thing to do is drill a small hole at the end of the crack to stop it spreading. Then check as

per Tinsnail. Then repair as per Harvomark. There appears to be plenty of clearance from the

A frame

Do you know what the series of holes are in your first image? Has someone tried to do a repair in the past?

My Pal's 2004 Clubman had a lot of movement between the body and the A frame. Unfortunately the van was written off after a minor collision because the frame & floor was so rotten. I had my suspicions the floor was soft at the front but never had the chance to check it out.

I screwed a batten in place to hold it together while I started repairing the crack.

Hi. Well now, I have a Lunar Ariva (August 2015) with one 3" crack where the gas strut attaches to one side of the front panel and smaller cracks on both sides where the hinge brackets are attached. Not very clever for a new caravan. It's our third Ariva---no problems with the previous two. This caravan is 40kgs lighter than the last one in spite of a built in microwave. Seems to me that that they are overdoing weight reduction. Fortunately the entire front panel is now in the process of being replaced under warranty---no quibbles. I wonder how many more have cropped up ??

Question is, will the replacement also crack?

Its hard to work out how these cracks have started, as it would be better to know this and take some remedial action before doing a repair, which might otherwise need to be repeated. ..

 

The gap is really quite large and a significant failure. The centre portion is over the chassis, so should have been adequately supported, unless some packing under the locker floor has been removed/lost. Perhaps there has been some abuse with the locker being seriously overloaded with heavy stuff that has repeatedly impacted the sidewalls on the move?

As said further up, drill a hole at the very tip of the crack to stop it spreading before you attempt to fix it, or move it again. .

Took it to Woolacombe this weekend and it got worse. The 2 brackets underneath that take the weight at the front of the box are bent. Emptied the box of any weight, inc bottles. Got home, and hey presto, can hardly see the gap in the cracks.

 

Winter job is to patch repair, and get a little reinforcement under the floor of the box to take any weight. Quite a big bottle came with the van (13kg), which has to be tilted to get in there. Will have to get rid of that, and put smaller ones in.

 

Thanks for the replies

If I remember correctly from previous Lunars we owned, a 13kg bottle did not fit into the front locker so your assumption about too much weight in the front locker is probably correct. Have you checked the nose weight of caravan as it should probably be about 7% of the MTPLM?

No I haven't, but I guess you would have to do this on level ground?

 

My van is parked on my slopped drive, and I don't fancy taking the bathroom scales on hols with us. :D

I have a Milenco calibrated nose weight gauge for sale. It is about a year old. The only reason we are selling is because the nose weight on our caravan is 140kg so we have to buy the Milenco nose weight gauge that can read 140kg. PM me if interested.

Reinforce crack by melting stainless steel strip into the crack, a 10mm strip will be fine, sand down, fill, pramie and paint. I have taught this type of repair to the motor trade for about 25 years now and I am yet to have a failure. No need to drill using this method.

 

Can I ask, what is all that white stuff spread liberally around the crack area?

First attempt at repair.

 

Melted white lego blocks in acetone. Turns out to be an almost perfect colour match. Found it on another forum.

 

Drop lego blocks in acetone until they melt into a mayonaise type consistency. Start filling in small pea size amounts. The acetone evaporates and leaves the white goo solid like the original lego block. Then use wet and dry to take it back. If you keep the stuff in a jam jar with a lid, it stays like that, and the acetone doesn't evaporate.

 

My intention now, following some of the advise on here, is to reinforce the back with fiberglass etc, then fill the front with the goo.

 

Need to reinforce the bottom of the box as well.

Not sure about the match from here and in testin we have found it to have very little strenght, play with fibre glass but it does not stick well to abs due to many reasons.

 

I must admit though I only do proffesional long lasting repairs, this may not what you are looking for.

Thanks.

Hadn't seen that one. Much more comprehensive.

Can you pick that Lego stuff off with your finger nail? we could when we tested the idea here in the workshop.

I'd be tempted to try the same stuff that plumbers use on abs pipework

Not very easily.

It will not give you the support you need without a good flat piece bonded behind it.

 

Have a look at this picture as it will show you what I am talking about, I have repaired hundreds of bumpers and trims doing this since about 1985.
