Also bought (2) 5-153x for rear only to find out that the front and rear uj's are the same(the 5-153x was longer)...This is a 97 SW(auto of course ) anyone have a definitive answer on this...same or different for front and rear...thanks everyone!
The usual answer is...it all depends.
It seems there is no rule as to which are used. I used Neapco 5-0001 on the front of my 89 diesel pity the 5-153 don't fit they were half the price. I haven't needed to do the back yet.
