My Makita LXDT04 lost the ability in the trigger to control the speed so it has an excessive high speed only.
It also goes in the wrong direction, right is left and left is right.
I have 2 others but it would be nice to have a 3rd.
What part do I need to replace?
Brush? Trigger?
I have no idea.
How old is it? Have you contacted Makita?
What happens when you pull the trigger half way?
If its till in the warranty period I would deal with that first. I would think it was the trigger but I’m confused by the direction being messed up something with your tools circuity is really messed up.
Makita.com, find parts list, order new trigger and switch. Unlike brushless, there are no electronics to control speed etc… They are simple to fix. Should be a $40-$60 repair. Takes about 30 mins if you diy.

$27.50 for the switch, $4 for a new fwd/reverse lever, $9 for new brushes and a brush holder (might as well if you are taking it apart anyways).

No I haven’t contacted Makita, it’s the first impact drill I owned so it’s at least 5 years old.
if I pull the trigger halfway, it just goes to a high speed – not a speed the tool comes standard with.
I took it apart once when the drill stopped having the torque to turn something and when I put it back together it had this ultra highspeed thing going on so I’m sure I put it back together wrong.
Niw that I recall, I guess the primary issue was that the drill no longer had the torque to turn a lag screw enough…like it was skipping instead of turning the lags.
Would that be a brush?
I kbow whatever else is going on I’m sure I can reassemble it properly, I just need to know the root cause here.
The brush just transfers voltage to the commutator. Sounds like you didn’t wire the switch correctly.

I had the same problem with a hammer drill. it was caused by a broken wire contact on the motor sensor that is part of the trigger assembly. Cost me around $40 total, shipping and part, and about ten to fifteen minutes of my time to replace.
At 5 years old, you are better off just replacing the unit since these impacts can be found on ebay for roughly $50.
