Trailer suspension siezed. can it be freed up?

Got a trailer with braked axle but the suspension has seized, its that indispension type

tried a ton on it but no joy

Loads of fresh grease and pressure on and off not just a sudden shock load and maybe a bit of heat?

No grease points as it's greaseless.

Cant apply heat or I will melt the rubber inside

Hum don't know then. The only arm type ones like the indespension ones I used before were greased. Granted they were quite large ones for a trailer that weighed 3.5t. WD40? Lol

These are rubber inside a tube and are seized, probably due to rust on the inside of the tubes
Think I'll turn it on its back and use the WD40 and a bar to try and free them off.
Pity cause its a good trailer with brakes, handbrake new jocky wheel etc

Yeah time and WD or a good penetrating oil. Apply try and move leave for a few hours and repeat.

Good lube up, tyres to max pressure, then load it up to near max weight (use a 'solid' weight rather than a vehicle with suspension), go find a bumpy road and try to rattle it free.

Had it full of stone so well over a ton and drove it about twenty miles but not freed up at all

It's possible the rubber inside the suspension unit has hardened with age and is fubar unfortunately.
Is it in a compressed state as if it has sat for a long time with a heavy load on it?

^^^^^This.
I have a boat trailer on which the rubber in the units had gone absolutely rock hard. When i replaced them due to corrosion on the tubes I cut one open out of curiosity & the rubber had no 'give' left at all.
The new units have made a considerable difference. (From Trailer Tek, decent prices & free delivery)
