Chirping in my Front End

Dear Hive Mind,

I have an 06 WK Laredo, with 155K miles. I replaced a seized caliper on the front driver's side along with the rotor, pads and the hub bearing assembly. I also replaced the rotor, pads, caliper, and hub bearing assembly on the passenger side. I ran out of daylight before I could get to the differential fluid change.

It drives MUCH better now, not pulling to the side and no scraping from caliper, and also accelerates and of course brakes much better.

However, now I get a chirping / squealing sound in the driver's side, but only when turning right, above 10mph or when turning very sharp.

Due to the noise of the sticking caliper scraping / pads squealing I can't tell if the sound was there before. I will say that hubs were badly rusted to the knuckle, and the driver side hub was scraping when i turned it by hand.

Could the extra heat / resistance plus all the rust have damged the CV joint in the axle?

Thanks everyone!

When you put your pads on did you grease the calipers first

I used the blue caliper grease...but i will readily admit that I did a much better job on the passenger side.

I will try re-greasing them, and doing not only the backs of the pads but also the tabs that slide in the clips.

I brought up CV joint because in my ZJ when the driver's side U-Joint went out, it made the tires chirp on that side.

However this does not sound like tires chirping, it sounds like metal on metal.

Ive seen the shields do that after a certain speed and when turning wouldnt be a bad idea to check

Threw the dust shields away... they got bent when i was trying to hammer off the rusty hubs. Also I don't really like them, I've had rocks n stuff get stuck between them and the rotor before.

Have you been off road since you did the breaks

I have not had it off road, sir. I'm going to try re-greasing the backs and the mounting tabs of the brake pads.

Soon as I get home I'll re-grease the pads with the blue grease, and also going to re-torque all the bolts, including the axle nut.

Then I'll report back.

So it took me a couple days to get to it but today I took the wheel off, re-torqued the axle nut, (with an actual torque wrench this time ) and then I took off the caliper and the pads.

I replaced the clips that came with the caliper with the ones that came with the pads, because one of them looked a little bent on one side. I greased the backs of the pads generously with the blue grease, then I greased the tabs on the pads and the grooves in the clips with more of the grease.

Put everythign back together and now the noise is gone.

Thanks for the help guys!
