Putting in bushings/endlinks - Do I need to jack it up?

[EBInterceptor]

I'm about to go back out in the garage to do put on my new bushings and endlinks. Haynes says to jack the vehicle up. I personally am not in the mood to pull out my jack and stands. So can I do it without jacking it up? I just don't know what sort of tension is on the endlinks when it's sitting so don't want anything to jump out at me. Alright, that's it, hopefully I can get a response soon!

Thanks,
Mike

Scratch this, I didn't jack it up. But a word of advice. Don't work on a vehicle covered in snow. I've been getting dripped on all night. Fighting stubborn bolts and have water drip on my face is a true Chinese water torture
