Squeeking i can hear squeeking while running

It is hard to find squeeks, It could be bushings, struts, tierods, balljoints, even engine and transmission mounts. The worst one I found after five other people they said was in the dash. vynil was dry and most everytime you hit a bump it would squeek. I sprayed it down heavily with armorall and cured the squeek. Good luck

if you can hear the motor running,and if this unit does not have a belt shut off switch,the motor will run even if the belt is broken,the squeaking noise earlier was probably the belt starting to slip on the drum,replace the belt and drum glides when repairing,they are relatively inexpensive and as long as its torn down replace these too

Acc. squeek noise due to linkage issue, get it lubicated.

Regarding the clutch, you check the links, clutch plate springs condition. If there is wornout parts get it replaced. Gear shifting will be solved once you fix your clutch problems.

Mudflap hitting the ground?

you have a bad ujoint on your front drive shaft. remove shaft and replace the bad one but i would replace both. its squeeking cause the bearings in it have turned to rusty powder and are dry, the bad one will be easy to spot

check your ujoints may have a bad one.

do you hear the squeeking in the truck only if so then its the little o ring plastic in the peddle makeing the noise.

change your struts

Probably serpentine belt to loose.
It is common. Have it checked.
Also can be water or oil getting on belt and it starts slippering and makes the noise.
Good Luck
