What are Tapered Bearings and Why Use Them?

Tapered bearings are better than roller ball bearings at handling forces exerted on the bearing during cornering (known as axial load) in trucks and large cars. 

Roller ball bearings have spherical ball bearings between two straight rings (called races). Tapered bearings use tapered rollers shaped like flat-topped cones and two races angled from the outside to the inside of the bearing. The greater the angle, the more axial load the bearing can handle.

Your model came from the factory with tapered bearings. This type of bearing handles cornering forces better for trucks and large cars. Roller ball bearings work well for smaller cars, but replacing a tapered bearing with a roller ball bearing will result in increased wear and faster failure.

Positive Mold Technology

Improves durability and performance by allowing for even wear. Eliminates brake fade and glazing, generates less brake dust, and promotes a longer-lasting , better performing brake pad.

OE Grade Multi-Layer Shim

Reduces noise and vibration

Environmentally Compliant

Meets the Better Brake Law standards

Thermal Scorched

Accelerates the break-in process and enhances stopping performance from the first stop.

100% CNC-Machined to Exact OE Specs

Balanced to reduce vibration.

Cast from OE Grade Alloy

Manufactured from OE Grade G3000 Casting Alloy.

Non-Directional Surface Finish

Helps ensure smoother, quieter, and more effective braking.

Precision Engineered

From the highest grade SAE 1055 / 65Mn high carbon steel to exact OEM design.
100% Factory tested to precise OEM tolerances.

Highest Quality Materials

High quality, multi-lip seal reduces the intrusion of dirt and water. Heavy duty grease resists high temperature, moisture, and reduces intense friction.

Direct Fit Replacement

Guaranteed to fit and function correctly for your specific application.

will this fit the 5.3 liter engine?
Aaron S April 11, 2016
Yes it does and you cant bit the package for the price
Leo E April 11, 2016
Yes it will. I put this on my 04 GMC Yukon.
Danny R April 11, 2016
Breaks are based on tonnage not engine. If you have a 1500 4WD in the proper year range this should fit; if you have a 2500 or 2WD it will not. Check the OEM numbers listed against your model.
Christopher F April 11, 2016
Yes my chey tahoe has the 5.3 liter and they were a exact match to the stock hubs and brakes
Dirk B April 13, 2016
Engine size is not a factor. If you have a 1500 4wd in the proper year range they will fit.
I S February 6, 2019
Do you have this pad/rotor/hub kit for a 2004 2WD Tahoe?
Jaylin B May 3, 2016
We carry all the components for your model, just not in a kit like shown here
Brian F May 3, 2016
Who makes this kit?
Matt H September 1, 2016
I do not know the origin of the parts but I have them installed for over a year with no issues.
Michael G September 3, 2016
We have a few different aftermarket companies build these parts specifically for us, as our 1A Auto house brand. They are manufactured to the same OEM specifications as the original part that came with your vehicle. If you have any further questions, please dont hesitate to ask.
Brian F September 7, 2016
Mine came with Brembo rotors & pads. The bearing was in a white box. I recognized the brand but cant remember it now.
R A July 14, 2017
The Rotors and pads were by NAKAMOTO. The wheel bearing and hub were packaged with only part numbers indicated. Instructions included torque specifications for all vehicles the parts fit.
Anthony M September 6, 2017
Do these brake pads make a lot of dust?
Donald P October 10, 2016
I Cant say they do but I live in the country. I drive on dirt and I use my pickup as equipment. Im satisfied with these very much and pice was great.
Ross H October 10, 2016
No
Pat S October 10, 2016
No they do not. With normal regular vehicle washes you should not see any accumulation on your rims.
Michael G October 10, 2016
These are the ceramic pads, and will generally cause less dust than a semi metallic pad.

Great wheel hubs
I would buy again. Awesome hubs good rotors. Fixed my issues
March 22, 2017
kit needs a couple of parts
Have only had them on the Suburban for a few days. everything seems fine. great price and would buy again. My only compliant is that the brake pads do not come with new brake hardware. you should also consider buying new castle nut and hub mounting nuts. if you have to buy them from the dealer they are really pricey. The other thing to know is that the video shows the hits coming off with a few whacks of a hammer.... not in this universe. look up some youtube videos on how to remove. I used the power steering as a hydraulic press method after about 2 hours with a crow bar.
April 5, 2017
Easy, fast, and no hassle
So much better than the quote from the parts store locally..if you can wait for the part its way more beneficial to order this way
July 7, 2017
Excellent pricing!! Fast shipping!!!
Will definitely be ordering from your company again!!! Cheapest price and really quick shipment!!
July 14, 2017
The price is very good for the kit , all parts seem to be of good grade. Installed and completed in 1 day easy. Not bad for a retired 65 year old mech.
July 20, 2017
Extremely Pleased.
All the parts in the kit were an exact fit for my 2003 chevy 1500 express. The pricing for the kit was the best I could find after checking on line and local auto parts suppliers. What amazed me most was the speed of delivery with free shipping. Ordered on Satirday, parts arrived Monday afternoon. Certainly would recommend this company.
July 30, 2017
Great price
Your video was great so was the parts all went together as in the video all the parts are from China and from I can see they were made with great material we will see
July 31, 2017
silverado bearings
the bearings where good and the rotors where also good but the pads metal backing was a little to big and the slot where it fits over holder was to small. After milling the slots a few thousands bigger and trimming off a bit on either side of pad they fit good. overall satisfied with purchase.
August 28, 2017
Great Fit. Great Price.
I replaced both front hubs, rotors and pads for $165! Parts appear to be good quality and fit perfectly. Arrived quickly. Would have been $1,300 at shop.
November 1, 2017
Great
99% positive. Only thing I can think of would be your listing. 1 place says "hub assembly 1 ea". Another says "sold in pairs"
March 26, 2018
Perfect Fit - great product
I was traveling right before the 4th of July week and wheel bearings started making some noise. new exactly what it was. ordered parts from 1aauto.com and received within 2 days.fast shipping. Install was a breeze, especially with a perfect fitting product. Thanks 1A Auto.
July 17, 2018
2000 Chevy Silverado
Not sure exactly how long it has been since I installed, a few years now, as far as I know no problems!
December 16, 2018
Great price factory fit!!
I Had the passenger side front wheel bearing start to make some noise on my 03 Silverado. So I started checking prices to replace this part. When I got to 1A Auto the price was so reasonable that I decided to replace both front bearings and put on new rotors and pads at the same time. The brake and wheel bearing kit still came in under the price of 1 wheel bearing at the local auto parts store. Parts came right to my door in a couple days. They were a perfect fit and they are quality parts. I will definitely order from 1A Auto again.
February 5, 2019
Great transaction
Very easy to find parts needed, easy to order, shipped very quickly.

i ordered Brake and wheel bearing it from 1AAuto. The parts arrived in a timely manner and fit perfect on my vehicle. They were also cheaper than i could find anywhere else. I would definitely recommend 1Aauto to my friends and anyone else needing parts.
April 12, 2019
Fits and works perfectly
2004 Chevy Suburban LT stable track everythings well feels nice and sturdy the box that it came in was about 70 pounds I have absolutely no complaints excellent product so far Ill get back to you in a few months
April 13, 2019
Got moneys worth quality product
Great fit easy to install
April 16, 2019
Excellent
Very impressed with the quality and how easy the service was, very fast delivery, I highly recommend
June 14, 2019
Almost Perfect
Everything fit perfectly on my vehicle. My dog chewed up one of the ABS lines that came with the wheel bearing, so I tried using the old lines with the new wheel bearing and it trips the ABS when you get close to a complete stop, and will eventually show up with the (ABS) and BRAKE light. Attaching the 1aauto ABS line fixes the problem, but just wanted to point this out as I didnt know it would make any difference.
June 26, 2019
Good
Good for the price
August 4, 2019

Brake and Wheel Hub kit
The kit came on time. It was what I was looking for. I was shopping around for parts and only needed wheel hub assembly. This kit came with rotors and brakes. It was good purchase for the price. Helped me get back on the road. Parts fit my 2002 1500 Chevy Suburban 1500 LT 4x4. Thank you 1A Auto. Will be back for more purchases in the future.
November 21, 2019
