Replacing front lower control arms, weekend DIY or best left to the pros?

Car is officially aligned!


The only flag they had was that the FL caliper is seized (which I already knew)

I am not sure I’d necessarily recommend this as a DIY project, but reading that would not have stopped me before. Instead, here is what I would recommend if you are going to do this.

  1. Buy all the bolts and nuts! I naively figured I would be able to reused mine, so had to panic order them on eBay halfway through.
  2. If you do not already own one, get a reciprocating saw (sawzal) and a CARBIDE blade. I used 7 “metal” cutting blades and didn’t even get through half a bolt. The carbide one ate right through everything without an issue. I got a wired saw from Wickes for £45, and it worked totally fine.
  3. If your shocks start expanding even with the lower control arm all the way down, remove the upper control arm and take the shocks out entirely.
  4. Give yourself way more time than you think you need. In total, this project took me 7 days, working an average of 4 hours a day after finishing my job.
  5. Having a ball joint popper, splitter, etc was extremely helpful for one of mine which just would not release itself.
  6. Put the car back on the ground (both sides) before tightening everything up.

Below is a mostly complete list of the tools and supplies I used.

  • Breaker bar (duh)
  • Sockets from 10mm - 19mm (assorted drive sizes)
  • 3 different size ratchets
  • An adjustable pipe wrench
  • Wrenches from 10mm - 19mm
  • WD40, Copper Ease, and Fast Release
  • 2x Jackstands
  • The jack that comes in the car (Wouldn’t recommend this as it takes forever to get it up and down)
  • Assorted screwdrivers for prying
  • Hex key set (I think sizes 4, 5, and 6?)
  • Wheel chalks (I used 4x4 beams I had)
  • Rubber mallet
  • Reciprocating saw (AND CARBIDE BLADE, I CANT STRESS THE CARBIDE BIT ENOUGH)
  • Wire brush
  • Lots and lots of paper towels and latex gloves

And finally, here are the videos and guides I found helpful
