it started when i lowered the car on coils. i got wheels aligned, still had the problem. it starts around 40 then end at 53. i faster i go when driving the less it vibrates. i took my car to a honda tech. and he said i need shorter axles for my ride height. so while waiting for my axles i f@#ked up my differential by keeping the car lowered. so now where i am now, i have a new diff new driveshaft, new axles. AND IT STILL VIBRATES. the tech said the wrong axles were put onto the car so now im waiting for different axles with the supposivly right ride height. can anyone help me out and give me some info? i still have old axles idk if there still good or not.

 

swapped bad 1/2 shafts for bad 1/2 shafts? meaning, the buckets are worn.

have you done ANY research here on the board?

i'm not saying that's your problem for certain but .......

have you had the wheels balanced lately, maybe you 'threw" a weight?

bearings worn on the rear hubs cuz the axle nuts were never torqued properly?

 

Lowering the car does not hurt the dif.

Your Honda tech is incompetent (its amazing the amount of them that are completely clueless). I assure you 100% you do not need different axles. You likely just accelerated the bucket wear process which had already begun.

Search axle bucket swap. $0.00 to fix it.

If you get rid of your high quality Honda hollow-tube axles, and put some aftermarket solid shaft axles in, then you will REALLY know the meaning of the word vibration.

Keep you original axles, simply swap the buckets from left to right.
