Matrix FWD L4-1.8L (2ZR-FE) (2010)
Backlash:
0.10 to 0.15 mm (0.00394 to 0.00591 in.)
If the backlash is not within the specification, adjust the side bearing preload or repair as necessary.
NOTICE:
Measure at 3 or more areas on the circumference of the ring gear.
26. MEASURE TOTAL PRELOAD
(a) Using SST and a torque wrench, measure the preload (starting torque) with the teeth of the differential drive pinion and differential ring gear in
contact.
SST : 09556-16011
Standard total preload (New bearing):
Standard drive pinion preload plus 0.7 to 1.3 N*m (7 to 13 kgf*cm, 6 to 11 in.*lbf)
Standard total preload (Reused bearing):
Standard drive pinion preload plus 0.29 to 0.49 N*m (3 to 5 kgf*cm, 2.6 to 4.3 in.*lbf)
HINT
For a more accurate measurement, rotate the case bearing forward and backward before measuring.
(b) If the results are not within the specification, perform the procedure below:
(1) Select a thicker or thinner side gear shaft washer for the RH side, and then install the rear differential case bearing outer race (RH side
only).
(2) Repeat the total preload measurement.
(3) Repeat the ring gear backlash inspection.
(4) Repeat the differential ring gear and drive pinion tooth contact pattern inspection.
