I use this tool on a regular basis. Astro Pneumatic tool 78830. Pretty much three tools in one. I use this to remove pressed in hubs and to remove rusted in place rotors and drums. 78825 to install. Thank you for the video. Thank you to Astro Pneumatic for making quality tools at a reasonable price.

Great video as always. There's actually the same number of adapters in the two sets. OTC: 13 adapters, 3 cup stacking plates, 1 hub install adapter Astro: 13 adapters, 2 cup stacking plates, 1 hub install adapter. The additional extra large cup plate and the cup (few required applications but can be nice to use) is available separately as 78825XLA. Should be everything. That's not to say one wouldn't work better than another in certain situations. Our application list also goes up to 2019 and lists around 300 more applications, albeit not in a large bound book.

I have the Astro 78825 and I bought the Astro 78830 to go with it. With these two, I pretty much have everything the OTC kit has in it (less an adapter or two). If I recall, my MAC guy wanted almost $500 for the OTC. He recommended the Astro to me, and sold me BOTH kits for a little less than $200. Seemed like a no-brainer at the time. In hind-sight it was, by FAR, the best deal. So far, I found the Astro 78825 kit covers all of the domestic and Asians that are my bread'n butter. I don't get much Euro-trash in my shop, so I just haven't found the need to expand on what the Astro kit already has in it. BTW: The Snap-On guy sold me a ball-bearing washer that works on the Astro puller screw. It helps quite a bit. I don't know what the Snappy number is, but I'm sure your dealer can find it.

Keep it up Enjoy the videos I have learned so much from you and I am a 45 year mechanic I work on the 18 wheelers I have always work for a dealership getting to the end of my career

I was banging my head looking at Amazon comparing these tools. I thought they were the same thing. Here you are, uploading EXACTLY what I was looking for. Thank you!!

Thanks for the video Michael. I had both but gave the Astro kit to an apprentice. Great tools for the job.

I have the Astro kit and done Alot of bearings with it. Great kit, no issues at all.

Thanks for the great information, and have a happy Easter FRM

I have the astro version and I have been very pleased with it as well!

My wife got me the Astro kit for Christmas. I thought it was cool, but I rarely see press in bearings. Then one day we got two cars that had this style bearing. We saved so much time.

That looks like a good tool to have. I've been doing them on a regular hydraulic press.

I have the OTC hub grappler. Its an awesome tool well worth the cost. Good vid.

Love the grappler. Made a lot of money with it.

I have that Astro kit love it! I added a bearing on the forcing screw. Happy Easter & stay safe FRM!

I go online and get a ball thrust bearing and it really helps cut down on friction and transmits torque to removing bearings.I use EP grease on the threads and never had to replace any parts yet.

i absolutly love my Astro Pneumatic 78825 kit

Price is right and it gets the job done. Own this kit as well and it's a great way to get additional adaptors for multiple uses.

Awesome video! I moved to a shop that doesn't have a on car wheel bearing kit. I HATE trying to set up knuckles in presses so I'm looking to buy my own kit. I don't use the hub puller in the OTC Hub Grappler kit. I found it to be a bit of a pain sometimes. I got a Lisle 40100 hub puller that is AMAZING! This Astro kit is like 1/10th the money but I REALLY like that eccentric washer in the Hub Grappler... It definitely helps center things if they don't start off perfect. One shop had lost their washer and I used it without. I found bearings were jamming up a lot. Would have to give centering taps with hammers quite a bit but almost never had to with the eccentric washer. I'm thinking I'll probably drop the thick cash on the OTC kit. I've used it a lot and never ran into a situation where it didn't work.

I have the Astro kit and although it's been a few years IIRC since I was replacing the hubs along with the bearings on a car with around 160k miles on it, I just punched them out from the inner part of the knuckle using either an impact socket or one of the smaller adapters (or both, I forgot). I tried a slide hammer but just found this method to be quicker and more effective.

After trying some of my co-workers sets, I debated getting something like these. It didn't really seem like much of a time saver for me but it was easier on my body. One problem is up here in Michigan the rust usually makes it too hard to get the bearing retainer out while the knuckle is on the car. At that point I might as well use the press. I can normally do press in wheel bearings in 30 to 40 minutes my way or the Hub Grappler way. I do like the idea of using the adapters on the press. Maybe I'll get the Astro set just for that reason.

@MrSupernova111

I replaced my front wheel bearings recently and that's what I did. I bought a Maddox kit and used the adapters to press the bearing. I like the idea of using an impact ratchet to press the bearings but I worry that the impact ratchet and adapter kit might not always be strong enough to get the job done using them that way. Anyway, a 20 ton press with the adapters worked great for me.

You can get the Astro version of the stand alone Grapper kit (78830 Heavy Duty Hub Drum and Rotor Puller Kit) for a little less than the Grappler one, PLUS it comes with the drum puller arms too. Anecdotal statements I have seen indicates it actually works better in some cases because of how the threaded section of the screw is compared to the Grappler screw (don't know if they are interchangeable).

Ive found permatex assembly lube to be the absolute best forcing screw lubricant personally

I like the OTC tools as they are made in USA. I just recently bought the Grappler kit and their Super Ball Joint Kit. Quite expensive but the price through Summit Racing seemed to be the best (added week to get in hand from shipping though). I love that the ball joint tool is made from actual steel instead of Chinesaluminum. I ended up with a '11 Escape at bargain price, needs a windshield, liftgate (rust) and front bearings (it's like driving on saw blades...LOL). Once I sell the truck I'll have some darn good tools from that profit.

I love my OTC Hub Grappler

The OTC is something similar to what I use which is a Super Shark Hub Puller Removal Kit Made by Old Forge a extremely excellent designed Piece of equipment it for certainly makes the job simple and very easy most definitely a super time saver with the addition of the old forge bearing Press removal kit

I use the evertough one from Oreilys works pretty good.

Love the channel

Thank you 👍

No probs with the Astro kit but same as you, I had to replace the forcing screw on the OTC Hub Grappler and Bosch gave me a hard time about it. I told them it was the first use of the kit and the cup crushed then the screw got bent. They eventually sent me a replacement screw and cup.

Great video 👍

I think you mean a combination of Astro 78825 and 78830?? looks like the 78825 is just the adapters without the rest of the setup that the hub grapler comes with?

I don’t know if anyone is aware of this, but this exact set is on sale at HF for like $80 under the name “Wheel Bearing Adaptors.” You replace the forcing screw with one from an OTC Hub Tamer and boom.

I used a sacrificial socket to get the hub out. Came out with a couple of whacks using a 3lb sledgehammer.

Is there a tool for removing the race stuck on the hub? I've tried cutting it and wacking it with a chisel before always end up going too deep and nicking the hub shaft. We don't have an oxy acetylene torch at the shop so I can't do the spin on a pin of some sort and heat it to drop it off. I've heard mapp gas won't get it hot enough.

Thanks Mike , Do you always use new hub ? Old hub ? Or depending on situation ?

Hub Grappler. Well worth the $$$$$

does it need to be a brass hammer to fix if it’s cock eyed? mine was cocked eyed and i kept tightening with a brraker bar until the bar broke. when i got the bearing out the inside where the bearing susposed to sit was dented in and peeling out so it wasnt perfectly round anymore. does this mean i need a new knuckle now?

Quick question; can I leave the knuckle attached to the vehicle in order to keep it steady?

There is a comment here that the OTC stuff is made in USA. The last few tools I have bought from OTC are not. I also used to consider this a reason to buy from them, but no more. I have a lot of OTC things, including my 75 ton press. If they continue to charge as if selling "made is usa", but not deliver it, I'm done. I cannot afford to "subsidize" a company that is just flipping things from Taiwan or China. Sourcing from there does not make them bad products, but it sure makes them cheaper products. Not all Taiwan/China products are the same, either. I have found all Astro items I've bought to be excellent, and I'm starting to look to them first.

So it looks like a version of the China Freight but with less adapters. Hopefully has a better jack screw as those are made of the crappiest metal possible.

I have a Chevy Astro cargo van. Should I use the Astro kit on this?

I can't believe y'all use that thing. I just use a shop press, just about the same amount of work and I get to sit down while I do it!

my shop got a hub shark and i hate it with a passion. i use my snap on ball peen stile hammer and beet the hub out and then just use my shop press for the rest. the bearing that is left on the hub i cut into just enough to use my air hammer to remove it. but most of the time i usually recommend a new hub when replacing press stile bearings because of previous experience of them being damaged from the customer driving to long on the the bad bearing.

Have you ever had to use the small puller in the otc kit to remove inner races that get stuck on the hub?

THaT GuYs 1 Channel for a diy who presses in maybe one a bearing a year no that’s 500$ you can spend on other tools but for a shop that does 15 a week yeah worth every penny especially when the car is from up north and removing any bolt takes hours of work.....now on the other side cars from up north sometimes have to be used on a press I had one so bad my 50 ton press was pushed to the max before it broke loose

So for less money you get lesser of a tool. But if you purchase a slide hammer and the add on kit for the Astro you right up there in price with the otc kit anyway.
