It is only when I max out the turn on the steering wheel. It sounds like metal on metal. I can't see where it is binding/grinding.

Any ideas on what to look for? I must be getting old.

 

Are you sure its metal to metal...because all Toyota's make a little sound when turning and you have the strearing wheel cranked all the way to the left.

 

On 2nd gen toyotas there is a steering limater in the form of a metal peg and a dished metal face located behind the right side of the wheel. Trun the wheel all the way to one side and see whare it hits and you will see what I mean. The pegs have plastic caps from the factory but once thoes break you have to put a dab of grease on them regularly to stop the noise. It's really obnoxios. It happens when the weel is cranked and you go over a bump right? Take a look. Once you know about this problem you can simply dab more greas on whenever the sound comes back.

 

The "groan stopper" covers are available online at various online auto parts stores as well as at the dealership. I've found them for as little as three dollars and change each. At that price you might as well buy a bunch since they will wear out. I prefer buying them rather than going with the grease solution since the grease still allows metal on metal contact.
Heck, maybe buy them and grease them. It may prolong their life.

My 89 did that. It took me awhile to figure it out. I replaced the plastic coated stud.............never thought about the grease thingy.

 

Could it be a tire noise? The tire rubbing?

 

Do the 3rd Gens with Rack and Pinion still have that stop?

 

my taco has a stop (non adjustible) but it doesent look like the knuckle touches it much, i think that the steering travel is built into the rack

 

I had that problem on my '88 sr5. I just lived with it and it was super loud, as if my entire suspension was falling apart. Never figured out what the problem was...

 

Thanks very much! I just ordered a couple of the groan stoppers for my truck.
