I had the same problem with my wifes 2018 Terrain, the lugnuts caps had swollen and rusted so taking them off was a difficult process. I went to amazon and looked up some of the many styles and choose the one piece chrome style, no caps to worry about, cost about 35 bucks for 20 pieces and they came the next day.

 

@Urbansuburban do you have the link to the lug nuts? $35 for 20 is not too bad on the pricing.

 

Ditto on Amazon. Our 2013 had the swollen lug nuts, Dorman makes one in the the same style that's one piece.

 

Sorry for the delay Superdave, I did those just after the first winter so it would be almost 5 years now, i can look it up if amazon lets me go that far back.

 

@Urbansuburban thanks for your reply. No worries if you can't find the info. Costco here charges about the same price per lug nut, but I think they are just capped. I am just curious where to find such a good deal because I did spent time looking when I need new ones. I went with Costco because even Canadian Tire charges about $17 for a pack of 4.
