hey guys, i was on a cruise today, and as we left the park where we had lunch, they had the cattle grids, then straight after it a speed bump with the spikes on it to stop you going in the exit. and now after going out the exit, whenever i accelerate, i get a thumping noise/feeling when accelerating. i can feel it thru my steering wheel, gear stick, and a bit thru my pedals, and can also hear it quite obviously. i cant hear anything when cruising (80kmh) in the cabin, but i thought i heard a bit of a grinding type noise when cruising past a wall over a bridge. i couldnt hear anything when decelerating but when i was going down hills i could sometimes hear a clicking sound like a cv joint. it sounds like its coming from the LHS aswell.

i have checked my wheel nuts.

my thoughts of possible things causing it atm are my cv joint, maybe an engine mount, loose suspension bolts/nuts.

a few months ago a guy and me from work did my lhs inner cv boot and i think he put the little bits for the tripod on the wrong way, i think, im not entirely sure.

i cant really think of any other info right now, but im going to go put my car on stands and have a look.

thoughts/opinions?

p.s. its still driveable, just slow accelerating and i havent taken it over 85kmh. i babied it home from north of narre warren to home at 80kmh.

more about the cv, its been making clicking noises every now and then since we did it, maybe the cv couldve flogged out the intermediate/half shaft?

i just drove it on the jack stands and replicated what i was doing on the roads, and it was only ever so slight compared to actually driving it. i checked the mounts on the lhs and found the lower one to have one bit of it completely split and apart.

i think this could be the issue.

thoughts?
