My front wheels keep getting in side position and makes it hard to push. How to set it differently?
I am sorry, but that either requires servicing (which, I know, is hard to find in most towns and cities), repair (again, hard)... or at least god maintenance. I recommend going through this guide of ours, helping you with all the cleaning and maintenance your stroller most probably needs - and if nothing helps, it might be it is broken internally. try all you can, clean, oil your parts before deciding if perhaps a new one wouldn't be the only solution.
