Mountain Buggy Terrain: loose chassis

Problem:

Do you have any tips to tighten up Mountain Buggy Terrain? Pram is shaking/vibrating side to side when jogging and even while walking but obviously not as noticeable when walking.

Sugested solutions:

Tightening the screws shown aroun chassis should help a little. Regarding the wheels, check that the tires are evenly distributed around the rims and that the wheels are properly inflated. Check that the ball bearings are in order Les mer
