Steering & Suspension Kit
Im very happy with this kit, all the parts are there. Great value & fast shipping. It could have been packaged a little better, some of the parts are heavy and ate thru the box. Other than that, very happy.

Exactly What I Needed
I noticed my suspension on my 2002 Ford Explorer XLS was squeaky, creaking, and that the ball joints were worn. This all in one kit had everything I needed for a DIY front suspension rebuild for the best price I saw out there. After renting the right tooling for pressing the lower ball joints into the frame, everything from there on out was a breeze. The vids posted by 1A on YouTube greatly helped as well. Once everything was installed, the squeaking and creaking stopped. After an alignment, the Explorer drives like new again.

Customer Q&A
Ask a question to 1A Auto customers who purchased the product
Are the upper and lower ball joints or outer tie rod ends greaseable or do you sell an upgrade to this kit with greaseable ball joints and tie rod ends?
Anthony G March 12, 2017
These parts are sealed and are not greaseable. We do not carry a kit that are greaseable at this time, unfortunately.
Tim K March 12, 2017
How is the durability of the product been rated? I want to make sure I dont pay less to only have to be doing this job again in a few months.

The average life expectancy is around 30,000 to 70,000 miles based upon driving habits and road conditions.
Alex P October 11, 2017
This will be the expectancy for this particular set, while other vendors provide the same expectancy.
Alex P October 12, 2017
