Trailer suspension unit

[neilhope]

I've managed to bend the arm of the suspension unit on my trailer - unfortunately it's not the type you can take off and just bolt on a replacement.
The unit comes straight out of the trailer's 2" tubular cross spar
and there doesn't seem to be any fixings or bolts to remove and replace.
Anybody come across this type of unit before?

A photo or two would help.

I know of no trailer that has the suspension an integral part, though I can see how it could be welded on.

Usually, though, the spring hangers arer bolted on, either through the frame rails or using U-bolts.

i would suspect you are looking at a full axle rather than suspension units ......if its bent then its a replacement .....most trailer parts companies will supply one ......you just need to give them your chassis dimensions and they can get one made to suit ...or you could try the original trailer manufacturer

either way it doesnt sound like a cheap repair .....an example axle on ebay ....made to your size is around £240 ... a replacement pair of braked suspension units is around the same

pictures would certainly help identify what you have

Thanks for the replies.

It's a home made trailer by the looks of it - I got it when I bought the boat a couple of years ago.

I could possibly chop the units off where they come out of the cross spar and then weld on a couple of mounting plates and then bolt on new units.

They seem to be mini units/hubs/wheels.

I'll post some pictures when I get a chance.

Neil,

I replaced a couple of unbraked units on the trailer that came with my boat - Total cost was about £100 including the fixing hardware. Memory says the braked versions weren't much more expensive, unless you bought them with all the brake gear...

Most trailer places will be able to sell you a pre - drilled plate to weld on & bolt the individual units on, the fun bit however is making sure they are absolutely lined up. Not sure what your boat is, but if it's an SR4 you can probably get away with an unbraked axle, which will keep the cost down. (unless you have a particularly lightweight tow car of course!)

I think the cost of an unbraked axle probably isn't too far off a set iof individual suspension units.

I've looked at a few different options - welding mounting plates to the axle beam, fitting a beam with mounts attached, getting a new full beam axle with units as it is now, but they all work out about the same £150 - £200 plus price range.
The cheapest option would be to weld on mounting plates and fit new suspension units coming in at £100-£150 for parts only, plus I'd need to cut off the existing suspension bits and get my hands on welding gear or pay for someone to do it for me pushing the cost up to that £200 plus mark again.
My friendly trailer centre will do it all-in for £200 and even lend me their flat bed trailer to take it in!
That'll teach me to avoid concrete bollards as I go around narrow corners - still at least I know I'll have everything tip-top for my trip to Wales in August.

Trailer suspension all sorted.
Existing units cut off at axle, mounting plates welded on and two new units bolted on.
Splashed out on a couple of new wheels and tyres for all-in total of £260.
