the tag on my differential says S828A 55 88 9H06, what does this mean? do i have LS?

 

First part is the plant code:

S828A

Second part is the axle ratio: There should be a "3L" preceding the 55 if it's a Limited Slip. If it's open, it should just say '355' I believe.

4th is the ring gear diameter, in your case an 8.8 inch.

5,6,and 7 are the build year, month, and day, in your case, August 6th, of '99. (9=1999, H=8th month [and there is no 'I' in the sequence]) and '06' is the 6th.

Too much info..... Need to know either what precedes the '55' or what the axle code is on the sticker inside the driver's door.

there is nothing else by the 55. but my axle code is 19. what does that mean?

 

19 = 3.55 Non-LS
