You can buy original thermoplastic boots in Pakistan but only for local manufactured cars, they are usually called âplastic walay bootâ
They come with the correct grease already and following the correct cleaning procedure is mandatory before adding grease. Then you need a heavy duty tool to crimp its oetiker type clamp.
You wont be able to buy thermoplastic boots for any jdm car in Pakistan.
Cv joint grease is mostly an EP rated lithium based moly additized nlgi1 grease.
Modern ones are polyurea with no moly and usually are in pretty colours like bright blue or green. Make sure it claims to have a penetration of 300 and EP rating.
