Rivet Breaks and Punctures Case
Spider Gears/Side Gears Break
There are 2 styles of gears, cast and standard sintered steel. We see the cast gears fail at least 5
to 1 compared to the sintered steel gears. So we only install standard sintered steel gears.
Cross Shaft Breaks
There are two diameter cross shafts available, 16 & 18 MM. The 18MM shaft stands up to much more
punishmnet and is the only size we use in all our o2j rebuilds.
Cross Shaft Roll Pin Breaks & Corss Shaft Punctures Case
This is the most common failure for all o2j rebuilds that come into
our shop. There is a single 5 mm roll pin retaining the cross shaft. We double roll pin the shaft with an SAE type pin inside
the metric pin. Next we grind a small "V" groove between the cross shaft and differential. Then a small root weld is applied.
We haven't had a roll pin failure since using these procedures.
Rivet(s) Breaks and Punctures Case
We remove all factory rivets and repalace them with a better than OEM bolt kit made by
Can we build a differential you can't break? NO! But we can make the weakest part of your transmission better than new!!
