Exhausts and Engine » Drive Shaft Rubber Boot - NBU 30 PTM

I often refer to this video (along with @Grumpy's) when greasing the splines. At the 10:09 mark, the mechanic shows what they're using to seal the rubber boot back in place.

"STABURAGS NBU 30 PTM"

I looked it up. Pricey stuff.

I'm currently just using white lithium grease but am finding it doesn't "cure", ie coagulate to a soft rubber form as well as whatever the bike came with did.

Has anyone found a more affordable (but worthwhile) alternative to the STABURAGS product and does it in fact become more "stretchy but plasticized" for a stronger seal?

As some have found out, this is an important seal. I'd be inclined to make the investment in the Klüber product recommended in the repair manual. The lack of response from the forum might imply that most folks and shops are sucking it up and using the recommended Staburags.

You could always ask your local BMW dealer in Lone Rock.... (Nice area of the world, by the way.)

That said, I saw one of the LT guys used Dow Corning High Vacuum grease - which I used to use in the lab. This won't cure to the same state as the Klüber product, but will provide a nicer, more durable seal than the lithium-based grease. I looked up current prices (yikes), and found that it is about the same/gram as the Klüber Staburag, but is available in tubes with half the amount (25 g) and could save you 20 bucks.

Ray, thank you for the reply. I certainly appreciate it.

I like the price of duccrazydave's option better but I need to trust that the product will do its job in both sealing the boot and *becoming semi-rubberized* (ie "cured")

... and I don't (trust it), or at least not yet.

For all reasons positive and to protect my bike (I ride this thing like I just robbed a bank), I'd love to read more arguments for/against the Mission Automotive product ( https://amzn.to/3BVzRbr )

Teach me a thing or two about why this is or isn't a comparable option.

Remember to have fun. When in doubt, get out and ride.

Just to be clear,

Everyone knows this post is about seating the RUBBER BOOT and *not* lubricating the shaft splines, correct?

Gotta check just because money being money, I want to make a decision without having to spend on return postage ;-)

I decided to try the Mission product after watching GG's driveshaft service videos. To my knowledge, no dielectric grease "sets up", as the recommended product described in the earlier posts.
