So I got a bit of suspension problems.
I ran Armstrong compression rod bushings until recently I changed them to OEM bushings due to wear and noise.

In the process I also installed a 15mm spacers on the front (my rear wheels are a bit wider) so I did not put any spacers on the rear.

So the changes I have done to the suspension are:
1. New bushings
2. Spacers in the front.

As a result my front wheels stand about 5mm wider than rear.

The issue that I have now is steering pull while changing lanes or hitting small bumps.
Could it be caused by my front wheels standing wider than rear or bushings?

 

I'd go back to poly. The only time my steering ever tracked straight was when I had poly. Regardless of how many alignments I'd get. Have you got alignment numbers?

 

yes, I aligned it after the install, every thing is within specs
I do not recall this kinds of play in the steering when I was on OEM bushings in the beginning .

 

Are your tires new? If your tires were on there before the new alignment/ bushings, and they've worn a certain way they'll try to track the same way as before the work. It'll just take some time to get them trained. If they've been grooving one way for awhile, they're gonna want to continue that wear pattern.

 

I'm guessing it might be the spacers. Why not try taking them off for a week to see if they are the culprits or not?

 

Tires are new. I put them on with new bushings.

It's actually easier (not cost effective) for me to replace bushings. When putting on spacers I had to cut my studs off so they don't stick out pass the spacer in order to mount wheels, so taking spacers off would mean changing studs and that's a time consuming process.

 

There are lugs for that

 

there are no lugs for that.
