While changing the oil in my '03 Tundra last week I noticed both front drive axles have been throwing grease from the inner boots. Closer inspection reveals no torn boots, appears the metal band between the larger and smaller inner boots has just loosened allowing grease to escape. I haven't heard any grinding or clicking while driving. Truck has 123K on it, as far as I know these are original axles.
As far as I can tell my options are to remove and replace entire axle assembly, or remove and rebuild with a "boot kit".
My questions are: 1 - Based on mileage should I just replace the axles, even though there is no evidence (i.e. noise) indicating the CV joints are bad? 2 - If replacement isn't necessary, is there a way I can re-grease the boots and tighten the bands without removing the axles.
Thanks for the info.
