Sounds like CV joint grease. check the rubber gators haven't been damaged when replacing wheel bearings. There will probably be a coating of grease around the suspension area
I’ve seen them greased back up using a syringe then repaired using vulcanising bike tyre patches, but that was an only fools level bodge on a car that wasn’t worth fixing properly!Looks like the boot has a small hole in it and by the looks of things it's easier to fit a new/refurbished axle instead of dismantling it to replace the boot. Does anyone know which aftermarket brand is good quality or if there's anywhere doing decent refurbished OE stuff?
Has anyone had much experience with patching boots with silicone rtv or similar to get me a couple months down the road or is that a complete waste of time?
