GM IFS Front Drive Axles
In 1983 General Motors redesigned the front drive axles on its four-wheel-drive S and T trucks. The new design was an independent front suspension (IFS) for better handling and ease of manufacturing and repair. In 1988 GM added IFS front drive axles to its full-size-truck lines (K trucks).
The Rear Up Front
With four-wheel-drive and all-wheel-drive vehicles being produced in such huge numbers, these trucks and cars have become an important source of repair business for our industry. Transmissions and transfer cases are now a huge part of the repair and reman market. It is also obvious that these designs use both front and rear differentials to transfer power to both sets of drive axles. This has effectively doubled the amount of differential work that will find its way to the repair shop.
