LOL - defo installed correctly! The big L & R gave it away! (I assume that the LEFT and RIGHT mean as you are sitting in the drivers seat????!!!!)
Just had it on ramps - got the GF to sit in the passenger seat and undone/retorqued pivot bolts just incase. Then done the same on the drivers side. Also while I was under there I had access to the idler arm so I took it off and inspected... It looked ok as far as I could tell. The parts I got weren't Lemf' unfortunately but the other side has been perfect since and they seem like they're good quality. Balljoints are all good and bushings seem as new.
Checked the seating of the spring on that side too - all ok, and tightened up the top mounting nuts for the suspension. I had previously checked the torque on all balljoint nuts too.
EVERYTHING seems tight down there which is really bugging me. Also, its only when the wheel is turned to the left. OR Jabbing the brake at low speeds... This is the key I think, but I just can't think what it could be after checking the rest.
Luckily though while I was down there I noticed a small leak from the sump plug as it has loosened... Tightened it up and all good.
Bloody car keeps me on my toes... (normally walking because its broken! LOL!)
