squeel

On my drive to work at my country job....celeste started to make
a squeel/noise at about 15 miles per hour.The squeel increases in intensity as the car rolls faster..the squeel is coming from the left front.the squeel is not affected by increasing engine rpm..the squeel is lound enough to be heard above the stereo at higher speeds.

What do you guys think it could be...wheel bearing?brake hung up?

car stops and drives excellent..just an annoying noise.:confused:

is the hub getting hot to the touch after the squeel:confused:
and have you checked for cats or small children stuck in the hub:D
if not cats it should be a brake pad sticking and making noise and heat

this may not apply to the GT: wheel bearing assembly went out on dads 1 ton chevy this summer and would make squeals above 5-10 mile an hour. get worse with speed, didnt produce any noticable heat....check the tire for uneven wear, as a shot wheel bearing can contribute to that.....i'd still bet baz's brake pad theory is probably the cause though.

I'd check the bearing for heat as mentioned above. Next I'd jack it up, with the wheel still on tourqe it up and down, side to side, and see if their is any play. Then pull the wheel, look over the rotor try rotating the wheel to see if the brake is catching. Fixing squeels now before they get worse and potienatially causes more damage will save you time and $$$. Good luck to you.

Also keep in mind that the Opel rubber brake hoses are notorious for coming apart on the inside. This allows the pressure to reach the caliper, but doesn't allow the pressure to bleed back off. So you wind up with the pads partially aplied.

Best to check it all out.

Good luck,
James

duplicating the squeal

if I rotate the hub in my hand it will squeal a bit....it is a little hard to turn...maybe 2 pounds of pressure or so....bearings look well greased and don't look burnt or broke form this view...


I would like to fix myself..but I have not experience..I will continue to study my manual..what do you guys think?

check to see if anything is lodged behind the backing plate, pull the caliper,2 - 19 mm bolts and then spin the rotor , then pull the wheel bearings if the noise persists, clean and repack, for the rear bearing you will need a new seal most likely, also semi-metallic pads squeel sometimes.

Bucky, you might want to pull the brake pads out then see if it still makes the noise when you turn rotor by hand. Its possible something is caught in the pads, or the noise could be from the pads themselves.

it is a very easy process to replace the bearings. a cotter pin and a couple bolts thats about it.

squeel or squeal

sorry I misled you all on the brakes...as I listened with the window down and 30
mph(50kmh for those in metric)..the noise was not outside..but coming from the dash...the speedomter was working smoothly ..but not jumpy...anyway..I unhooked it and noise was gone..the guy at OGTS said it was a common problem and I should try to lube the bushing ..next to the dial:D

but now I know how to do the wheel bearings...I could always rebuild a bicycle crank and wheels...so this will be a little more challenge..when the time comes.

it is about 40 degrees here and its dark at 5:30pm...celeste
started great and ran great with the new pertronix and coil....
except for the speedometer cable.everything is working like
"almost new"..not bad for 212,000 miles on the clock

as someone said in a prior post about the opel gt "there is really nothing else like it"

I disconnected my speedometer becuase the speedometer was chirping, squeeling, annoying what ever verb tickles your fancy. When I disconnected the speedometer the cable dragged on the road and wore through it, it sucked becuase it was a NOS cable too. I got another cable at carlisle and installed it today and the speedometer still squeels as expected. where should I lubricate it? how do I lubricate it? graphite?

squeal

i had the same thing. put on protective eyeware and a mask, lay on your back and find the cable input location at the back of the speedo. there is a bronze bushing there.

i used spray lithium grease, w/o pulling the instrument panel. i sprayed both ends, its been fine.

The speedometer stopped squealing, I sprayed some silicon spray into it and then took one of the old pieces of the speedo cable and attached one end to a drill and the other end to the speedometer and spun it at 75 mph for a while and then more silicon spray, the drill for a little longer and then one last spray and reconnected the real speedometer cable. It couldn't be quieter. Now I just have a sound coming from the front driver side wheel but it stops when I put the brakes on....so I think it is some suspension component and when the brakes are one it puts force on the control arms thus pushing them back and silencing the noise.
