Never heard of such a thing. Never had my mechanic, who I’ve used for 20 years, ever made that recommendation or observation. Run away!

 

Sounds like you use yours like a family minivan. <;~D

Try loads like this, needs a doubled suspension... then yer'll see how good the mottor mounts are!


Not to worry. I creep along the flats twice a year, between my storage yard and the launch crane.

 

I wondered too about the motor mounts in my 06 Sienna ( 2nd gen) None are leaking , a sign that they are bad nor does the engine " jump" when the accelerator is tapped. Yes , I have changed the dog bone a couple times (206k miles on the van) . I put this question to the Care Care Nut on you tube, a Toyota technician and he says if there are no symtoms of a failed mount dont change them "just because".

 

dealership has something of a reputation for over selling repairs.....all 4 mounts. Now they estimate 1600.00.

They didn't want to do it. Hope that the reason for the quote

 

Torque steer is a symptom of bad mounts. Does steering veer left/right when getting on it. Also the large mount in the back when it goes can cause serious serious vibration. Had one crack my anti-lock brake block it vibrated so bad. Came about pretty suddenly. It's a serious job.

 

Motor mounts, don't get me started.
In my experience with a '99, Sienna has lots of power for larger loads etc, once yer stiffen the rear suspension,, but the motor mounts are her achilles heel.

First big clue... flex pipe in the exhaust gets over-flexed.

Check mounts by... use wheelblocks, put parking prake on,, alternate between drive and reverse,, watch how much the engine shifts around.

Haven't really found a solution for my driving style.
Perhaps OEM's,, perhaps using a powerful bedding compound to fill in the hollows in the rubber- 3M-5200 would at some flexible toughness. Dunno.

Front axle shaft needs to be pulled for the under-mount,, a real pits for home mechanicing. ~$6-800 for full set re-re,, seems about par for the course.


...'the hill that I couldn't'' , but I sure did try. ...down in Baja.... the picture makes it look simpler than it was, and once I did a reconnesance on the E-bike,, I'm glad I didn't get further,, it goes way further up,, then a wayy worse down,, then a bunch more up's downs.. I'da been totally stucked! <;~0

If your going to replace it anyway you can cut a groove in the mount casting below the axle bearing using a cut off wheel. Careful not to cut the bearing. Hit the groove using a hammer and chisel, cracking it. 15 minutes. A little oil, remove bolt, c-clip retaining the bearing and the axle will come right out.

 

The bad azz mount is the big one in the back. Very involved to replace. I had one there fail and the vibration was so bad it cracked the anti lock brake unit.

 

Yeah, definitely a mother to replace! I've only done mine recently (all 4) for the first time in 260k miles. I live in a mild climate though. Also, I was able to hold out until I needed CV joints again (second set) which PROBABLY had about 15k left but I decided to bite the bullet because of some rotting of the boots. Anyway, your dealer is full of it, trying to sell you parts and service you don't need. Try and find a good indie mechanic in your area that maybe specializes in 'Yotas that is highly rated or a good one that friend recommend to you. That's what I do when I don't feel like wrenching on something myself.

 

Old thread reviving...

Well, been two years, what happened so far?

On my pre purchase insp. from a AAA approved indy shop, the mech wanted to do the same 4 mounts, the main mgr. checked it out, and told me to "just drive it".

I don't feel the need yet to replace, it was an $800+ aftermarket est. from mech who might have needed a boat payment too lol, I don't know, he also suggested another $800 for something else.

My 01' CE is at 91k, besides replacing the front vvt sol, so far so good. The oil pan leak is still there, bought a new pan, fipg, and a Fumoto valve for a future new mech to install for me. I would imagine a dealer adding another 0 for profit.

 

Where do you guys keep finding these low mileage, 1st Gen Siennas? Lol

 

Hiya Ed,

Of all the places I have been searching, Carfax, Auto trader, the web, the lists, the dealers, a few good ones came up on "Offerup", I would not have guessed that one.

Only a few had lots of dealer maint. records. I did not put much weight on how it looked, more on how it was kept up, and wanted 01' to 03', and more basic.

Hmm! I'll have to check it out! Mine is getting a little long in the tooth with 268k on it, but I'm gonna keep it till she's done since I got her in about '01 with 10k and I know everything I've done to it maintenance wise. But I love 1st Gen Siennas and would like to have another one around with about 100k. Especially with the non-vvt engine, since they're non interference. I even have an extra tranny on my bench that I rebuilt. It's actually the OG trans that I pulled about 7-8k ago for the current one the I rebuilt and put in when I began having problems with the OG at 260k. Anyway, I rambled on too much! 😂 Thanks for the info!
