Hey guys, got a question. I am replacing my front landing gear box and motor. The 5er is in my driveway and is raised fairly high. I have a sloping drive and I can walk under the pin. I am 5'7". My question is can I remove the motor and gear box without lowering the trailer? Will it fall if I pull those two item? I would like to do this without hooking to the truck if possible. Thanks, John.

What do you think is holding the fiver up? Of course it will fall. Hook up the truck and support and chock very well so the truck and trailer does't move.

You can possibly use a heavy duty jack stand to support trailer inlieu of truck. But you will need to support trailer somehow

On a slope, I would skip the jackstands.....use the truck.

From etrailer.com:

Question - "Do you need to place a support jack under trailer before you remove gearbox ? My tube on the gear side did not retract the same amount as the non gearbox side. I suspect gearbox may need replaced."


Expert Reply - "If you can level your trailer it is not necessary to add an additional support jack before removing your gearbox. The gearbox turns the screw that activates the jack, but it also has a fail safe that does not allow the jack to drop if the gearbox is removed. In the case you are not able to level your trailer, you will need an additional support jack."

All that said, I'm paranoid about being crushed. So, I'd hook it up to my truck for peace of mind.

These front jacks are a screw-type setup and will not fall if you pull the motor and gearbox. The motor and gearbox turn a threaded rod with runs in the matching threaded leg. That is what supports the trailer.

JMO, but depending on how heavy your trailer is, you might consider going to a two motor system like the Bulldog legs. That's what I put on our Fuzion and it works so much better than a single motor setup. Plus a side benefit is being able to move the legs independently to allow for uneven ground.

Having replaced landing gear 3x now I doubt the jacks will allow the trailer to drop with just removing the gearbox and motor. However, in this scenario where your under the front of the trailer I would either hitch to the truck or build up cribbing immediately behind the landing gear under the frame. Each time I've done this I've hitched up. Close quarters but very doable.

Been there. Done that more than a few times.

No need to remove leg if only removing the motor. The leg is not going to collapse.

Removing the leg is another matter. The motor comes off first. Best to stay on the truck for safety. If not, transfer weight onto blocks under the frame before removing anything.é
