split boot kits are NOT reliable, stop looking for shortcuts with such a critical item, CV axles are meant to last hundreds of thousands of miles with proper maintenance, and the outer boots on the front take the most abuse out of all 8 booted joints on the vehicle. The split in the boot that makes it easy to install is also a failure prone weak point in the boot construction which will be where it fails later on.
Do it right or do it twice people. GKN kits are $15 a side.
