Strut & Spring Assembly Front Pair TRQ SCA57003 - 1ASSP00157

Part Details

  • Quantity: Pair
  • Front or Rear Location: Front

In the past, replacing struts required specialized tools to compress, remove and transfer the old spring and mount.  Pre-assembled with all new parts, our complete strut and spring assemblies make this job much quicker and easier for the do-it-yourself mechanic.

Each complete strut & spring assembly contains:

  • Upper Strut Mount
  • Strut Bearing
  • Coil Spring
  • Boot & Bumper Kit
  • Gas-charged Strut 

Loaded strut & spring assemblies allow for a quicker, safer install than bare struts.  No spring compressor required! 

Trouble-Free Install

Includes the matched parts needed. New components over reused parts provide a better ride and save you from having to repair again.

Matched Parts

Not all shocks and struts are manufactured the same.  Mixing and matching can result in ride quality issues and decrease the life of the parts.

Saves Time & Money

Over buying the parts individually, or having to search different parts that are correct for your vehicle (because we did it for you!)

  1. step : Remove the top of the strut (1:07)
    • Lift the hood and secure it.
    • Remove the three 13 mm nuts in the engine bay securing the top of the strut.
    • Keep two of them loosely threaded just to keep the strut from flopping around while you work on the bottom half.
  2. step : Remove the wheels (1:37)
    • Use a 19 mm lug wrench to loosen the lug nuts.
    • Raise and secure the vehicle.
    • Remove the lug nuts and set the wheel aside.
  3. step : Remove the stabilizer link (2:03)
    • Use an 18 mm wrench and an 18 mm socket and ratchet to remove the stabilizer link.
    • A breaker bar can help get it loose, using the wrench to secure the back of the bolt.
  4. step : Remove the bottom of the strut (3:01)
    • Apply some penetrating oil to the two 18 mm nuts securing the strut to the steering knuckle.
    • Work the bolts out of the steering knuckle and strut.
    • Unthread the top two nuts and pull the strut down and out.
  5. step : Install the new strut (4:35)
    • Put the strut into place and thread one of the bolts through the bottom of the strut and the steering knuckle.
    • This secures the strut so you can secure the top three nuts.
    • Torque the two bolts at the bottom to 100 ft lbs.
    • Reassemble the stabilizer link.
    • Replace the wheel, using a star pattern on the lug nuts.
    • Torque the top three nuts to 20 ft lbs.

Best place to get parts
I don’t normally go back and write reviews but I will on this. I’ve been looking for new struts for my wife’s cars I’ve looked at other places shopped around then I stumbled across 1aauto never heard of them but I got to looking found the struts I was looking for they had them in stock and the best prices I could find on them ordering was simple easy shipped on time and got to my house in no time I was surprised it got here that fast. This will probably become my go to place to buys parts.

Could not be happier
Price was good. Delivery was quick. Installation was relatively simple. 1A Auto online videos are really helpful. I would suggest that replacing the stabilizer bar links should just automatically be done when replacing struts.

Is this the whole complete strut package? Would i have to buy anything else? Could i just buy this and switch out my struts and have no problems?
Shawn on Dec 31, 2016
BEST ANSWER: these are a direct swap out unit. No additional parts needed for this job
Is this two parts, one left and one right? Or is this 1 part that I need to buy two of?
Lisa V on Oct 24, 2017
BEST ANSWER: This is one left and one right. You wont need to buy anything else. Don't forget to get a front end alignment once they are installed.
