1998-99 DRIVE AXLES Differentials - Traction-Lok - 7.5", 8.8", 9.75" & 10.25" Ring Gear
DESCRIPTION NOTE:
Differentials are identified by inside diameter of ring gear. Traction-Lok and conventional rear axle assemblies are identical except for differential case. Information in this article is related to Traction-Lok differential case overhaul. To remove differential case from rear axle housing and for all other information, see appropriate rear differential article.
NOTE:
The 10.25" differential Traction-Lok unit is also referred to as a Limited Slip Differential on 1998 models.
Traction-Lok differential has limited-slip function. See Fig. 1 . Two sets of multiple disc clutches control limited slip differential action. On 7.5" ring gear, side gear mounting distance is controlled by 7 plates on each side: 3 steel, 4 friction, and a maximum of 2 steel shims selectively fit to control side gear position. On 8.8" ring gear, side gear mounting distance is controlled by 7 plates on each side: 4 steel, 3 friction, and one steel shim selectively fit to control side gear position. On 9.75" ring gear, side gear mounting distance is controlled by 8 plates on each side: 4 steel, 4 friction, and one or more steel selective shims. Plates are stacked on side gear hubs and housed in differential case. An "S"-shaped preload spring (7.5" and 8.8") or a Belleville spring plate (9.75") between side gears applies pre-load to clutch packs.
