Diff Washer 17x23x1 (2) Description · Specs. · Photos (1) · FAQ (1) ·   General Q: [email protected] on Monday, May 05, 2003 07:42:58 I have bought 4 pairs of these diff washers but none of them has a polished surface! If I use them they will damage my diff balls? What do you propose doing? Yours Alexandros Savvakis   A: Dear Sir It was found to be complicated for many customers to build the original diffs correctly, due to the two different sides of the diff rings. Now both sides are the same, and there is no need to worry abut correct assembly now. However, be very careful to break the diff in correctly! If I can help you in any other way just let me know.
