I am going to replace my 2000 s80 front shocks since they blown out, yesterday i went to Canadian Tire, the manager's computer shows there are two different front shocks for 2000 s80, but when i visited auto parts shop, the salesman there was quite sure they had one which is what i want, he even did not ask for any further information. So anybody here can help me figure it out? and any difference between right and left front shock?

i am going to remove and install front shocks by myself based on youtube and rent compressor from Canadian Tire, i want to know after i finished the work, wheel alignment is a must? thx for your help in advance.

 

Take off a front wheel and have a look at part numbers. They gotta be there.
I think I saw a sticker when I had wheels/inner arches removed last summer.

 

Thx for your help. Just come back from the auto parts shop and the guy there confirm this is what i want, he said my s80 is regular one.

do you think after finishing my replace work, i need do a wheel alignment?

thx.
