I need to do the sway bar links on my 05 1500, and am wondering do I have to jack the truck up to do this job? I don't think I do, but I don't want to risk it.

 

It depends on how much clearance you have. I have a 4WD and still can't slip under mine very far (big guy).

Makes it harder if you jack up one side at a time, so, if you don't have a floor jack, then you might try to find a DIY facility, where you can rent a bay and lift, for the job.
