Grinding in reverse

Question

My Lemans has had this problem for some time now and i can't seem to figure out where it comes from. Anytime i go in reverse and turn the wheel counter clock wise to a certain degree i'll hear a grinding noise. The wheels don't seem to be rubbing and i'll take any advice i can get because i'm ready to try anything to get rid of this incessant noise. Thanks in advance!

Pictures of your under carriage might help, if you get the chance. Does the noise sound like it's coming from the front of the car or the transmission or rear end?

I will assume it is from the front for now.  It is a metal on metal grinding? Are you running over size wheels and tires? Has the power steering pump or steering box ever been replaced or serviced? Is it possible the wheels or tires a rubbing or coming in contact with the inner fender or perhaps the tie rod ends when the wheels are turned at a severe enough an angle?

Those my initials thoughts without knowing more information.

Check the brake drums for a rust ridge.

it definitely sounds like it's coming from the front, i dont know if the steering assembly has ever been serviced. it does sound like grinding though. it only does it at this one angle in reverse, if it's turned more or less than this one angle it doesn't grind at all. if i can ill try to get some pictures up.

My recommendation would be to put the car up on jack stands, unlock the steering column so you can turn the front wheels and tires. Turn the wheels left or right backwards slowly and turn the tires until you get to the angle that you start hearing the grinding.

Once there look to see where the metal on metal contact is coming from.

      I've got a 1970 T-37 Tempest, which i recently learned through PHS is nowhere near original, so ive decided to swap the motor from a 350 2v to a 455, the 455 i purchased came with a TH400 attached, but is from a 1970 bonneville. The T-37 as of now has a TH350, So I guess my question would be what would need to be changed, if anything, to put the bonneville TH400 into the Tempest or would the TH350 handle the stock 455?
       
      Thanks, Sam

      Hey!
      I just noticed this loose-feeling wire and electrical connector on my 71 Lemans, and I don't know what component it goes to. It's on the passenger side under the hood, right in front of the wipers. 
      My windshield washer isn't working atm, so I'm thinking this could have something to do with that. 
       
      Thanks for any help!

      Hey fella's! New to the page. but i've been thinking of doing an Auto to Manual swap in my 69 Laurentian. i know these cars came with either a 3-speed or 4-speed, could anyone help to identify these transmissions? and possibly track down a clutch pedal/linkage assembly.

      Looking for a blower motor resistor for a 1973 Pontiac LeMans, US-built.  The car HAS air conditioning.  The blower control on the dash has FOUR settings, (lo - - hi).
      The resistor I have in the car now works on the lower three settings, but gives me nothing on 'hi.' 
      I think maybe it needs a very specific part from JUST a 1973 LeMans WITH A/C.
      Thanks in advance,
      Gary
