PROPELLER SHAFT 10 Fig. 18 Fig. 19 Fig. 20 Cover relief hole Condition of clamping strap for any damage specially at crimping portion. Free and smooth rotation of bearing unit in centre bearing assembly. The bearing should have negligible radial play. Condition of dust seals in centre bearing assembly. If any of the above defects are noticed in the centre bearing assembly, complete centre bearing assembly should be replaced. Condition of dust caps on propeller shaft and coupling flange. These are tack welded to respective components. Check both spacer rings for wear score marks. If found defective replace with NEW one. Replace defective parts. LUBRICATION PRELUBE OR LUBE FOR LIFE DESIGNS Universal joint crosses and bearings are prelube or lube for life designs and have no lube fittings. Special seals are used to contain the lubricant in the cross bearings in this design. Fig.18 Replacement of the cross and bearing kit is recommended rather than relubrication. LUBRICATION FOR SLIP SPLINES Apply grease gun pressure to the tube fitting until lubricant appears at the pressure relief hole in the plug at the slip yoke end of the spline. Fig.19 Now cover the pressure relief hole with your finger and continue to apply pressure until grease appears at the slip yoke seal. Fig.20 Caution : In cold temperatures be sure to drive the vehicle immediately after lubricating. This activates the slip spline and removes the excessive lubricant. Failure to do so could cause the excess lubricant to stiffen in the cold weather and force the plug out. The end of the spline would then be open to collect contaminants and cause the spline to wear and/or seize. LUBE FOR LIFE CENTRE BEARING : Centre bearing is packed with grease for life. No filling of bearing with grease is recommended.
