When Replacing Trailer Suspension Components does Axle or Frame Need to be Jacked Up

Question

Question:

Can I replace the equalizers and shackles from under the trailer and just put a jack under each axle as I do them, or do I need to lift the entire trailer and axles?

To replace suspension components like the Dexter EZ Flex Equalizers # K71-656-00 that you referenced you will need to jack up the frame and not the axle. Lifting the frame allows the suspension components to unweight which gives you ability to unbolt the components without them being under tension and without risk of the suspension falling apart and dropping the frame on the ground. For a jack we have the # ALL620471.

Wheel chocks like the part # 337WC24483 wouldn't be a bad idea either.
