After a couple of rainey days, I now have a crackle sound coming from the left/front wheel area. It only happens when I accelerate, so I’m thinking the “rising” motion of the front part of the car is when it squeaks. It doesn’t happen when I’m cruising or going over bumps. I’ve pretty much maintained the car myself for the past 5yrs, but never really lubed any part of the suspension. What type of grease should I use, all purpose??
