Grinding noise on coast after 21k miles

Gjkrisa · May 19, 2018, 11:29:39 PM

Just noticed some grinding it's been a week been driving with it just the other day got worse now can hear it louder and it's more consistent
First noticed about a week ago but thought it was other vehicles around me because I couldn't repeat it or understand when it was happening.

Not to be rude but the rims look very dirty/muddy. To me it seems like some of the dirt could be lodged in the brake pads against the rotors causing the grinding. (Or possibly in the bearings)

Yea kinda think so also but if in the break should have gone away by now I would think but I have been meaning to wash them I do not live with a hose attachment

You'd probably need to give the car a good wash and check to see if there are any leaks from the PTU, if the driveshaft is operating correctly, etc. in addition to checking the brakes for rocks in the dust shield etc.

How is the engine running, any issues? What oil are you using now and how many engine hours between changes? I think I recommended going no more than 100 hours in your case.

Currently amsoil 0w-30 I'll check hours later but definitely not related to engine does not change with rpms

Most likely something with the breaks as I slowly add break the sound and vibration get worse to a point then goes away maybe I'll try a hard stop 60-0

Usually mud or rocks don't stay stuck in wheels this long but also usually wash my cars soon after a bad mud bath.

Wear on the rotors seems normal. Do the inside and outside pads look evenly worn? Any rust buildup on the hubs?

Picture actually shows a line on side of passenger side rotor not the face it thought was interesting pads do seem even but low for only two years use

But waiting for the oil change to get a qualified person to look at it hopefully.

There is rust on the hub before I switched over to summer tires 3 weeks ago

Something could have been embedded in the pads causing grinding against the rotors. As the heat builds, especially if you have the stock pads, its more likely to occur. Happened more times in my truck than I would like to admit.

Lol and I understand Fairbanks can be harsh on the roads as the year goes. Spent some time there for a while myself.

Clean the Brake pads & Calipers with a pressure washer and start from there! It could be something lodged inside the brake pad caliper.

Probably got mud in your tires/wheels. Z

Rocks/debris can and will stay in a caliper pad a long time unless you remove them. Def start there 1st.

Fixed! So turned out loose lug nuts... All tires were loose driver was THE WORST 4 hand loose and the 5th only had maybe 20 lbs!
I did my own tire change over from winter so I only have my self to blame I'm pretty sure I did 100lbs on all lugs but only when still in the air never checked when brought it back down. :S

Well glad that's over. Now I know what a loose wheel sounds like and you will hear it before someone points out a loose tire.

Wow! Luckily you were Spared without incident! Glad it was something simple. Z
