Hi,
My 99 TL (176k miles) starts to drive pretty rough in the last couple months. The rough describe as vibration up/down from the front end.
I brought to the machanic, he told me the shocks went bad. I replaced the shocks. It doesn't help.

I brought the car back today, he said the engine mount went bad, need to replace it. I forgot to ask him which engine mount. How can I check to make sure which one is bad? Usually the front? or side? or back?
Where do you buy the engine mount? (honda part? advance auto part? napa?) any bolt/nuts/anything else need to buy along with it?

Thanks.

I bought these: http://store.excelerateperformance.c.../i-411798.aspx

 

Have the wheels been balanced, and the tires checked for out-of-round? That should have been done before new shocks/struts, and I don't think bad engine mounts cause vibration at highway speed...or ONLY at highway speed. There are usually other symptoms for bad engine mounts like hard clunks when putting into drive and/or reverse while sitting still.

 

Wow, that is expensive piece of rubber. $100 a piece.. thought around $50.

Yes, the tires balanced, rotated. It just happended last couple months. The shocks/struts had little oil leaking out (little wet around it). when it bumping on the road, i have my friend drive parallel with me, video type all the tires, it didn't bounces off normal, it seemed fine, but the machanic told it was bad, so just replaced them last week. Man, he just wanted to make $
The car only has the bumping/bouncing feel when at 60-65mph.
Low speed and high speed are fine.
There is a litle clunk sometimes when put it to drive/reverse. Thought this is normal because of the gears engaged in.
When at park, the idle is perfect, no vibrate, very quiet, always at 800RPM (even AC on, in gear or neutral, still at 800rpm).

The machanic test drive, he said 90% of the cause from motor mount, 10% from the tires/axels.

Additional info: the tires are just a year old (25k miles, still 60% tread left), axels/cv joints/tranny replaced at 125k miles (i drive hwy 25k miles/yr)

Thanks for your help.

 

Those have a lifetime warranty. The OEM carry no warranty at all. You will change them again if you intend to keep the car a long time. I'm at work sometimes 84 hours a week so changing parts twice isn't an option for me. It's hard enough changing them once. So with that in mind I look for durability when I buy things because it's hard for me to make time to do the installs.

 

Thanks MilwaukeeDave.

I forgot to mention, I jacked up the front, spin the wheels checking to any bump or out of round, but can't find any.

Strange thing is when I increase the speed from let say 0 to pass 65mph, you don't feel the bumping/bouncing vibrate. If I drive at constant speed anywhere between 58-65mph, I can feel it.

From your experience, is it the motor mounts or any other possible cause?

Thanks all.

 

shocks: oil leakage indicates blown seal--your shocks were no good anymore

bad front motor mount,,vac boosted and fluid filled= will cause running probs as well as allowing engine and trans to move out of position--stresses cv joints and more

the oe front mount retails for 150$,,our vendor dealers will cut you 25-30% off that
the passenger side is likely bad now too, 50 bucks for it
