This actuator was easy to install and works great! Fast shipping as well as a decent price are always a plus in my book. I would recommend this part for anyone who needs one. I'm a very happy customer!
Works great perfect fit
January 24, 2017
Easy install one tool, 15 minutes. 15 minutes first time. If I had to do it again probably be closer to 5 minutes.

They expedite shipping their parts out to the customer so quickly. Great customer service. Easy ordering parts that match your vehicle. I havent fully resolved my 4wd issue yet but I know Im getting closer. Thanks for all your support.
December 3, 2017
Part arrived fast, easy install. But I am still at a lost to why my 4wd is not working. I changed the switch on the dash, actuator motor, and this part on this review. Even check the fuses, made sure I had good ground and still nothing
Works flawlessly, great price.
December 6, 2017
Very easy installation with the videos. There are so many non-mechanical issues with a GMC 4wd system that you can easily address yourself with some research and Youtube. This fit the bill. Thanks 1Aauto.com.

Fit and worked perfect right out of the box! Thanks 1a auto!
May 1, 2018
Very happy with this purchase. Part was a perfect fit to OEM specs. Easy to install and best priced. Cant go wrong.
Not the problem :(
June 25, 2018
Turns out this wasn't our 4WD's problem either (most likely the encoder motor again), but we replaced it anyway since we had it. It fit perfectly and with the video was a snap to install.
Back Up
October 17, 2018
This item was purchased to replace the OEM actuator that became temperature sensitive (did not work when cold). Have not installed at this time, as truck is being used to close our remote Ranch for the winter and left in 4WD. Installation appears to be simple and straight forward. Plan to install later when vehicle is not in daily use.
Quality product

Fixed 4WD on 2010 Suburban
March 6, 2019
My 4WD drive stopping working during a snow and ice storm. I couldn't get out of my driveway because it wasn't engaging. I was getting a message on the dash as well as the shift light took many minutes before settling into 4WD. It didn't really go in though. I started reading and learned the actuator is a common problem. I watched the video from 1A Auto and price compared actuators. They actually had a fantastic price. Even if it was a little more I would have bought it because the video was so helpful. So I had the part in about a week. Luckily I have 2 other 4WD vehicles in the house. Part came and took no more than 5 minutes to swap. Next time I need to take it to the garage for something over my skill set, I will ask how much they would charge for that job. Thank you for helping so many people with your videos and for keeping the prices so low. Win-win!! -Dave in Michigan

Easy to install great parts

The video of how to install was great it made the job so easy! The part worked and fit. Thank you.
Exact replacement linear actuator
April 15, 2019
Exact fit for a failed actuator (which shifts the front differential in and out of 4 wd. Put some teflon pipe tape on the threads (it don't come with it as the picture shows), remove the old one and screw in the new one snugly. Don't forget to apply di-electric grease to the electrical connector, plug it in and you are golden. Use large Channellocks to remove the old one but screw in the new one by hand until snug.
Best place to order parts

Excellent service, received the items quickly. A1 has YouTube videos showing how to replace the parts that you buy. Parts fit perfectly and were easy to install. I would buy from A1 Auto even if they were more expensive (which they are not) because they make the installation easy.

Item arrived surprisingly quickly
Simple install made even easier by 1Aauto Youtube video
October 6, 2019
I determined my actuator was defective by visual inspection. I watched the 1Aauto repair video on YouTube and realized it was a straight-forward installation. I ordered the part from 1Aauto (out of appreciation for their video) and received the part quickly. The part installed just as shown in the video and my 4WD is now functioning correctly.

2002 z71 4wd actuator
October 6, 2020
I noticed the transfer case would switch, but the light on the 4wd button panel kept blinking. It changes to solid, when the 4wd is locked in, which made me think it was the actuator. Ordered one from 1A Auto, and it fixed the problem! Part was an exact match! Took 15 mins with hand tools.

I ordered a 4wd actuator solonoid for my 08 Silverado, it arrived as expected, the price was very fair, as most everything I have previously ordered from 1A, I'd recommend them to anyone not in an emergency rush, who's looking for cost-effective parts
Perfect fit
February 1, 2021
The actuator that I purchased was a perfect fit for my Chevy Silverado. The part was identical to the actuator that I removed. The part arrived quickly and on time.

Unfortunately for me I replaced the actuator and now is leaking oil from the electrical connector. And that is no suppose to be happening. Whe I removed the old one the connector was dry. It was probably a defective part.

Customer Q&A
What size thread is it on 4x4 actuator?
February 8, 2017
Justin W
I don't have the exact measurements. Our parts are designed to be exact replacements for what came with the vehicle, so as long as your year, make, and model match up with our listing, these will definitely fit and function just like the original. Please let us know if you have any other questions.

Does this actuator control both 4H and 4L? Mine will shift into 4H but not 4L.
June 19, 2018
Marvin L
Yes. This actuator shifts into 4H and 4L on my 2007 GMC Sierra 1500.
June 19, 2018
James M
Yes it controls all 4wd functions. If this doesn't fix problem there are only 4 components. Actuator (reasonably priced), transfer case motor (pricey), dash electric control switch (very reasonable and easy to replace), and finally computer 4wd modular control (very pricey). Mine would jump from 2wd to 4wd on its own. Repair shop couldn't determine the cause. So I started replacing parts front to back. Luckily I found the problem at the dash control switches.
June 19, 2018
BillyBob B
I would say no and advise you look at the gear box on back of the transfer case.
June 20, 2018
no it doesn't. that just engages the front drive shaft. you will need to look at the shift motor on the transfer case or the tranfer case itself.
June 20, 2018
Matthew V
Yes, this part control both 4H and 4L. We are unable to diagnose your problem because there could be multiple reasons why you're experiencing this particular difficulty. We suggest you take your vehicle to a reputable shop close to you to identify the problem.

4 wheel drive always shifts back to auto 4 wheel drive instead of staying in 2 wheel drive would this be the problem?
June 2, 2019
Irwin L
Yes it is very likely however I would see if you have any trouble codes first.
June 2, 2019
No I dont think so. This is just a solenoid that is controlled by the push button switch. My actual problem was a bad ground wire under the dash. Good luck

I spent a lot of money only to find out on my own that the battery cable on my 2011 Tahoe was causing the 4WD fuse to blow, not letting my truck go into 4WD, a loose ground can cause this as well. Try cleaning the Battery cable first. I bought this and it worked fine but it was NOT the problem. Took the truck to a mechanic only to have it happen again after 1000.00 "fix" I noticed the battery cable was corroded by coincidence I cleaned it and replaced the blown fuse...Been fine ever since!...GOOD LUCK! Hope this helps you!
