Hey everyone, new guy here. Been reading the forums a while but have never registered and posted. Happy Thanksgiving to the US folks!
I have a 2012 Mazda5 with about 122,000 miles. The car generally runs really well but has gotten to that age where things are going bad. Currently, there is an up/down type wobble sensation at low speeds (20-25mph), some vibration at higher speeds (45-55mph roughly) and there used to be some high speed vibration. Once the car warms up, the wobble seems to get a lot better but the 45-55mph shake is always there.
I initially thought tires, although I had a set of 70 or 80k Goodyears with maybe 20-25k on them, and I had them balanced several times. That never worked. I then went ahead and bought brand new General G-Max tires and had those installed a week ago. The vibration at high speeds did seem to improve. (75+ mph) but the low speed wobble and 45-55mph range vibration are still there. They actually seem a touch worse even.
I also have a slight shudder accelerating under normal load, 2nd gear it seems. I believe a shop put in the wrong transmission fluid. I've changed it out a few times and added some shudder stop and it was better but not gone. The motor and transmission mounts helped smooth it out too.
For context, I have been working through the whole vehicle this year plus I had work done in the previous year that needed to be done. The motor and transmission mounts are all new, idler pulley is new, intake manifold is cleaned and reset, CV Axle on drivers side was replaced last year by shop, I threw a new one on the passenger side earlier this year (then suspected it was bad and replaced it again last weekend). LCA's are new on both sides (Mevotech), stablizer end links front and rear are new Moogs, front struts (Monroe Quick struts) and stabilizer bushings were replaced by a shop 18 months back. Brakes are new, no vibration relating to brakes. Rear shocks and mounts are new, as well. Shocks all seem to work fine although I've been suspect of the front right strut mount for a while now, despite it being relatively new.
Inner and outer tie rods are new. Alignment is done. There are almost no obvious noises, minus a slight metallic clunk in the front quarter panel that has been there since shortly after the struts were replaced (I swear they bent the quarter panel).
I was suspecting tires, a bent wheel, or the CV based on the collection of issues. I've ruled out all three...well, the tire shop said they checked the wheels but I remain skeptical.
Does anyone have any thoughts as to what I should be looking at or has anyone had a similar experience?
Would a bent wheel or bad strut mount be reasonable possibilities?
