Service bulletin 68070390A

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Half Shafts If you are changing the half shafts on these vehicles due to boot leak concern then please understand that silicone boots are known to have a phenomenon known as ?boot sweat? because of the porous nature of Silicone, the internal grease can ?seep? through to the boots surface giving the appearance of a leak. During hoist inspection please thoroughly wipe and clean the boot with a clean shop rag and then carefully examine the boot for cuts or tears where grease is escaping from the boot. If a cut or tear is present or if the grease is leaking from the clamp area, please go ahead and change the half shaft.
