Van/Trailer Combo sometimes pulls left

[aarond76]

As noted above, sometimes the van/trailer wants to pull to the left, other times it will ride perfectly straight. I have experienced this with (2) different vehicle/trailer combinations. I used to figure it was a side wind but had the issue this weekend on the way home and no wind to speak of. Stopped for fuel half way home and then pulled straight the rest of the way home again. Seems like if I make a left hand turn onto the main road that's when I have problems, even after gradual right turns in the road. Any thoughts?

Hmm... Not a lot of information for anyone to help with. You say "(2) different vehicle/trailer combinations". Was the trailer the same for both? Or was the TV the same? Or were both different? What kind of tow vehicle(s) and trailer(s)?

If I had to venture a guess, I'd think sticky slide pins or sticky caliper on the front left disc brake. Road conditions play a big part too.
