help with front end alignment- inside tire wear...

can someone tell me how i can stop the wear on the inside of ONE of my front tires? almost all front end parts are new and was aligned not too long ago. i haven't hit any curbs, ect. but i did replace the guide rod mount on the driver side after it had been aligned so that's the side that's wearing. all other tires are fine and doesn't seem to pull to any side. so my question is, how can i adjust the toe in/ out on that side? i think that's what's off? i would like to stop as much of this wear as i can until i can get a proper alignment. a am getting a good set of tires and wheels on craigslist and really don't want to tear them up too.

Assuming you mean brake stay = guide rod and not guide rod = tie rod

I would expect your camber to be out rather than toe.

If you have a spirit level that has a bubble for the vertical, space it out from the rim of the wheel (don't align to rubber side walls!) to see if it is vertical with weight and wheel on the ground - roll the car back and forth to allow suspension to settle before measuring.

i don't have one, but by looking at the wheel it is slanted in at the top slightly.

Not ideal.

You can improvise with a bit of string and a small weight on the end of it. (Plumb bob)

The wheel should be as good as vertical

If it isn't then I'd check upper control arm parts first - just because they were replaced recently doesn't necessarily mean "they're good" these days. New parts quality can be shocking these days...

...I recommend an open minded systematic check of the front suspension to save yourself time in the long run.

had it up on jack stands last week when i was checking for oil leaks. i went poking through all the suspension parts and there was no play in anything. all the rubber bushings were in good shape too. what does that guide rod adjustment control? i may have not counted the threads right when i put the new one on. the alignment was done with really warn out guide rod mounts...

My only knowledge on it is specific mb tool they use for front end alignments, however on my 126 my rear tires sufferd from inside wear and was notified by MB that it was an issue with my rear springs sagging which caused the inside tire wear on the rear.

That wear looks textbook for excessive negative camber (wheel leaning in at the top). You will need an alignment.

If you are talking about the brake stay that goes from the lower control arm rubber joint just under the spring to the large ball-like joint on the chassis behind the wheel (sorry I need to make sure you're not talking about a tie rod)...

...then that rod mainly adjusts castor - but - when you change the length of that you also change the camber.

I can point you to a (long winded) DIY on this if you want

I am pretty sure I read that one of the causes of inner Tire Wear is the Upper Control Arm Bushings being shot.
I am going bey memory as I am at the Library on the computer and don't have My Notes with Me; so maybe someone can confirm that.

Also People have done Front End Alignments and 6 month-1 year later had the Uppper or Lower Control Arm Bushings Rot out on the and ruin the Alignment.

You don't need an alignment....you need to replace the sway/torsion rod bushings on the firewall under the brake booster and battery tray..
