Review: Muy buena calidad Review: I'm glad I chose this CV boot as a replacement for my daughter's 2010 Ford Escape. I had previously replaced a torn outer boot using one of the glue together boots and it ripped again within months. This time, I figured I would do it right with a one piece boot. I was convinced I would remove the axle end from the wheel hub and pull the whole CV joint off in order to gain full access and make it an easy job. Before doing so, I read the review where the guy bought the Walmart Hypertough Large Engine Funnel (search for part number HTLEF-2020) and cut the end off to make a cone to stretch the boot over so he could install without removing the CV joint. I was at Walmart a few days later, so I bought one just in case for $3. The following weekend, I went ahead and started the job. I removed the tire and wheel, brake caliper and then took the two bolts out the held the hub to the strut. I also took off the big nut that holds the axle into the front bearing. After that, you can just tilt the whole wheel hub piece forward on the ball join and get just enough room to push the axle out and remove the outer end from the wheel bearing so you have complete access. I cut the old torn glue together boot off and prepared to remove the CV joint. After a lot of looking, I couldn't see a clip that I expected to find to remove the joint. I fumbled with it for a while and just didn't see an easy way to remove it. Unconvinced about the funnel idea and sure I would split and ruin my new boot by stretching it out way too far, I figured what the heck, I'll give it a shot since I already had the funnel. I cut the big outer end off the funnel, cutting just enough so it would be a nice symmetrical cone. This left it the perfect size to slide over the outside of the CV joint and also cover the ABS ring that would surely cut the boot otherwise. I put the funnel over the CV joint and warmed up the boot with a heat gun so it was nice an pliable. On my first attempt, I greased up the funnel and tried to push the whole boot on right side out with the small end first. I got it about halfway and there was no way it was going to make it all the way on. I was getting a little discouraged and then remembered a review where the guy said he turned the boot inside out before slipping it over the funnel. That was the key, but here's what you need to know since it took me a few attempts: Flip the boot inside out and make sure you grease the funnel. Then start pulling the big end of the boot over the funnel. Get as much of the boot off the funnel and onto the axle as soon as possible. This is what was making is so difficult when I was first doing it and when I did it right side out. If you have the whole boot on the funnel at once, you are trying to stretch out the whole boot at one time instead of a small section. Pull the boot little by little up the funnel and again, keep getting as much of the boot off the funnel and onto the axle as possible as you move along. To my amazement, I got it to pop on and was easily able to flip it right side out. I had to triple check it because I could not believe it didn't split in half stretching that much. It worked...I'm amazed, but only after doing it this way. The last part of the job is inserting the grease, which is a messy but easy job. Just keep packing it into the joint as much as you can. If your boot was a mess, and dirt got inside, you should remove the old grease first. Installing the bands was the next new thing for me. I wasn't sure how the worked but eventually figured out that what you do is put them on by hand, as tightly as possible by clipping them so the little hooks go into the holes in the bands. Get them as tight as you can in this step because what you are going to do is crimp the square part the sticks up to tighten them. I had a tool (pictured) that is used to crimp underground sprinkler pipe clamps in the same way. You can get these tools at any hardware store. These provided clamps are just like a sprinkler clamp but adjustable. So put them on as tight as you can and then use a sprinkler tool as pictured to crimp the square part to tighten them up. I had to trim a little bit of the very outer edge of my universal boot to remove some excess material, but other than that it fits and appears to be just what I needed. I hope this helps someone! ## Features - One year *. - Can be used with the FB5000 CV boot installer tool - Can be installed without removing axle from the vehicle - Comes with clamps and grease - For cars and SUVs with small shaft ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00C2M76ME | | Best Sellers Rank | #96,724 in Automotive ( See Top 100 in Automotive ) #18 in Automotive CV Boot Kits | | Brand | FLEXX BOOT | | Customer Reviews | 4.3 4.3 out of 5 stars (2,232) | | Date First Available | 18 March 2018 | | Exterior | Machined | | Item Weight | 310 g | | Item model number | FB3000 | | Manufacturer | FLEXX BOOT | | Manufacturer Part Number | FB3000 | | Model | FB3000 | | Package Dimensions | 13.2 x 10.9 x 10.1 cm; 310 g | ## Images ![Flexx Boot FB3000 Small Shaft Universal CV Boot - Image 1](https://m.media-amazon.com/images/I/81IbNLK-c1L.jpg) ## Questions & Answers **Q: Can this fit a 2003 Mercedes e500 rear axle?** A: Good morning.

I knew my axle was fine because I myself accidently punctured the boot while changing the control arm. There was no issues other than that. I tried an aftermarket boot. Sadly I tore it because I couldn't get it through the cone. Then I saw this product. I oiled it with baby oil along with the cone and slipped it on the axle without hardly any resistance. This product works well and it will save you money. ## Frequently Bought Together - Flexx Boot FB3000 Small Shaft Universal CV Boot - Alpha Rider For Auto/ATV CV Joint Axle Boot Clamp Pliers Tool with 20 Crimp Bands -Ear Type Extension For Most Cars - HILAKE CV Boot Installation Cone Tool for Universal Stretch CV Bottom Tool --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ni/products/276492004-flexx-boot-fb3000-small-shaft-universal-cv-boot](https://www.desertcart.ni/products/276492004-flexx-boot-fb3000-small-shaft-universal-cv-boot) --- *Product available on Desertcart Nicaragua* *Store origin: NI* *Last updated: 2026-04-23*
