Will this attach easy to a standard walker

These are only for the Carex Classics Rolling Walker.

I bought a Carex rollator (6” wheels, 350 lb. Capacity) about 14 months ago. Only id on it is a tag: A2210021030 and weight limit. Great but the rear left wheel has lost 8 ball bearings and one of the bearing containers (I found them on the floor). The wheel is very wobbly now and may come off. Ot looks like the wheel assembly can be removed and replaced. Is there any way to just get a 6”, rear left wheel assembly to replace the one that’s broken.

Thanks for reaching out! All replacement parts available for your model can be found here: https://carex.com/collections/replacement-parts/products/replacement-parts-for-the-carex-steel-rolling-walker

Can you make the walker taller? it is to short for my dad

Yes, the handle height is adjustable up to 36" and can be done so using these instructions: https://cdn.shopify.com/s/files/1/0240/6504/8681/files/A33577_Rollator_rls-2b.pdf
