Iíve had my E revo 2.0 for 1 month now and Now my e revo squeaks when driving. There has to be load for it to squeak. Whenever I brake it makes the squeaking noise and whenever Iím driving relatively slow it squeaks as well. Iíve cleaned the bearings on the wheels and put 1 drop of 3-1 oil on the bearings. The sound sounds like itís coming from the rear drivetrain. Anyone have any idea on what this could be?
