Using Split Boots (Speedi-Boots) As Preventative Measure

[Squiggle Dog]

The CV axle boots on my 1979 300SD W116 are original, weather checked, and could split at any time. I was considering buying those cheap Dorman Help! Speedi-Boot split boot kits and installing them over the original axle boots. That way if the original boots split, the split boots will hold in the oil. I wouldn't have to remove the axles, either. But then if oil got caught between the two boots, that could possibly cause problems. I wonder if the split boots would fit over the originals, anyway. Just a thought as it would be a LOT less labor and would cost less than replacing them.

Would I be better off using boots from the dealer than those Flexx or Dorman boots? I usually use OEM parts and try to not be cheap. The Flexx boots look thin, while the factory parts look really thick and mine have lasted 30 years so far.

I consulted the factory service manuals for replacing the boots using OEM parts. It is a very involved process that requires a special cutting and beading tool among others. It is certainly not something that would be cost-effective to do myself. If I were to have OEM boots installed it would need to be done by a shop.

The Flexx or Dorman boots are probably the most cost-effective way to go as they slip on without the cans needing to be cut and beaded, spider joints pressed off and on, etc. Now I know why people are avoiding the OEM parts. Hopefully they will last 30 years like the OEM boots.

I used the split boots a long time ago, back in high school, on my 1977 Honda Civic CVCC. I think they may have lasted a month.

Unfortunately, CV boots are the kind of job you need to do the "right" way.

I am wondering if I should wrap the original boots with something to keep them from tearing.

But maybe I will use some Flexx or Dorman boots and reboot them since I am planning on changing the differential oil anyway. I also want to clean the breather valve and replace the seals. The differential side seals look easy to replace, but I wonder about the pinion seal.

I think I am going to clean the boots very well and then wrap them with Gorilla tape, and see how long they hold up.

http://www.astoria2000.com/main.html Ive used this boot before, very awesome you dont have to buy the 1000$ tool, you can buy these little prong that push it on and it works awesomely you dont even have to take them apart.

the funnel trick works supposedly

I will definitely use a Flexx or Dorman boot with a funnel when I do them.

But I don't really have $100 at the moment for parts plus all the time it takes, so I think I will just wrap the original boots with Gorilla tape and see how long they hold up.

I will still change the differential oil and clean the breather valve. When I do take out the axles to replace the boots some day I want to replace the side and pinion seals.
