has anyone done this themselves? if so can you give me detailed instructions how. my boot is shredded. i had a very loud annoying tick on acceleration and i thought i had a cracked manifold that seems so popular on these vehicles. i put on jba headers and the tick was still there and my stock manifolds were fine with no cracks. i read some other posts to this problem and found out that this boot could be the problem and sure enough my boot is almost non existent. i love my sequoia and tundra and this forum. thanks to all for your help.
