I think they were touched a long time ago for stepping bars. Could it be that the control arms are to tight I did them by hand didn't have a torque wrench at the time. now I do I saw that they a supposed to be 120 ft lbs I think mine are over that. What would the torque spec be for the body mounts. Thanks.

 

That could cause the rubber bushing to squeak. I don't know about a hydraulic pitch sound though. I don't know the torque on the body mounts, and depending on the condition of where you live they could break. So I wouldn't touch them just yet

 

its just like a chirp noise only once when going over bumps it's not like a repeated noise if it's more than one bump it makes only one chirp per bump. I live in Illinois but the truck is not rusted very badly there is hardly any in the front really only a little rust on the frame in the middle of the truck but I will take care of that soon. Thanks.

 

Also I am going to replace the coils anyway because they are also rusty and probably a little worn out over all the years. But it is a very nice truck and I plan on keeping it for a long time to come.

 

A chrip that's interesting because I have the same thing on my truck. Swaping out the coils isn't a bad idea but it isn't good. It's neutral, meaning they usually don't wear out unless you see the truck sagging but it is your money. I would recommend leveling coil springs if you want it level. All the bolts in the fenders?

 

When you torqued the control arms, was the weight of the truck on front axle (tires on the ground or the axle on the jack stands), or was it hanging loose? If later, that might cause noise and definitely premature wear of the bushings. Always tighten suspension components (which have rubber bushings) under weight. Bushings have metal inserts, so even if you go over the torque spec, you can't torque bolts by hand so much that it would habe affect on the bushing itself.
Same with body bushings, IIRC there is metal against metal so the bushing gets pressed only so far.

All new front suspension parts? Sway bar bushings and connecting links too? You can chase to the squeak by lubricating possible sources one by one.
Being a new part does not mean it would not have manufacturing error, or the material defect.

 

I tighten the control arms a little by hand then droped the truck down and then tighten them a little more. I have sprayed everything one by one and it is still there. And yest the sway bar bushings and end links are new.thanks.

 

Only other thing I can think of is motor mounts but they shouldn't be affected by bumps.

 

Are the various bushings rubber, or poly? If they are poly, squeaks are just part of the territory.

 

hi, they are all rubber. Also it doesn't happen very much at low speeds 25 and over it starts more.
