Bike squeeks from front suspension - Diamondback Edgewood LX 700c Men's Hybrid Bicycle

worn CV joints "click," but only upon turning.
worn bearings "grind," with a faint metal-on-metal sound.
So, squeaking in the front end is unlikely to be a CV joint or a bearing.
Squeak could be almost any front suspension component, but here's the reason to stop
guessing what it is and jack up the car, remove the two front tires and inspect the
front suspension: it could be a bolt/nut
that is loosening - and by catching it, and tightening it, you could save yourself the cost of
replacing the missing hardware. Also, be aware that an inspecting mechanic (if your state or
county requires a safety inspection (like Pennsylvania)) will inspect all components of your car's
front suspension as a routine component of your car's safety inspection.
Also:

1-----Inspect----- Coil Spring----- Broken or Weak Coil Springs.
2-----Inspect----- Sway Bar Bushing----- Worn, Damaged, or Faulty Stabilizer Bar Bushings.
3-----Inspect----- Steering Stabilizer Bracket----- Loose or Broken Steering Stabilizer Bracket.
4-----Inspect-----lower ball joints-----Loose bolt/rubber bushing to lower control arm.
5-----Inspect-----Upper Ball Joints-----Loose bolt/missing rubber bushing.
6-----Inspect-----Connecting Rods-----(these are the rods that connect the lower control arm to the
front of the frame) Check for loose nut (on the frame side), or loose bolts (on the control arm side).

Suspension needs to be greased.

you probably need new seals, sounds like they need a overhaul too.

Could be ball joints or tie rods check these.

is there a grease fitting on the swing arm? take out the bolts that hold the shock in place one at a time and grease them. use a bit of WD40 at all the pivot points until you find the source of the squeek.

The rear belt sometimes squeek on those bikes. Check if it's hitting the belt guard.

change your struts

When the car is stationary. Push down on the back (Boot or TRunk) as hard as you can a few times & listen for the squeek. It's more common in the rear suspension from my experience. It sounds like the bushings are gone or worn at the top of the suspension struts.
That's if it does squeek. You might not need your suspension replaced just the bushings as they are normally plastic.
Try doing the same by pushing down at the front of the car also as it maybe happening there too.

Hi Mike, grease is always a good idea ;) but seriously this could be a grease issue or stabilizer bushings, a bad shock or a broken or cracked bolt in the shock hanger have a look see hope this helps,good luck

SPRAY ALL YOUR RUBBER BUSHINGS DOWN WITH LUBE
