I'm on my 3rd or 4th front engine mount in 5 yrs...

No idea why, but they only seem to last about a year, then the inner rubber's all ripped out, meaning that the engine moves too much when you start it or turn it off, it kind of shakes.

when I fit a new one it cures it for a while. I've been fitting the complete bracket, but now I've got a replacement bush only.

I'm wondering if the diesel needs an uprated part ?? because the front mount Ive been using is listed for all voyagers 2001 onwards... most are petrol. It fits fine, just wondering if I should try the genuine chrysler part for the CRD, as the original lasted ages ???

Any thoughts

 

You say you need the mount replaced in about a year, how many miles/km you do in a year? And do you mostly ride city or highway?

I'm curious since I got a 2002 crd 2.5 since a few months and did 12K km already and I'm wondering if I will experience the same.

 

There may be some peculiar stress on the engine mount. When engine is idling is it nice and smooth, or does it shake and vibrate a lot? The kinetic energy from the engine has to be transmitted from it to the body and wheels via the engine and gearbox mounts, probably a twisting force. Is there something peculiar about this pathway, the drive-shafts, constant velocity joins, a splined shaft etc? I'd look in this area for wear or bent parts. The suspension is involved here too, maybe some of the road bumps are being transmitted to the engine, wrenching it about.
Just some ideas to be going on with.

about 10,000 miles a year, (16,000Km) mostly town driving

Car has 150K miles on the clock now

 

The engine mount(s) primarily deal with the torque from the engine.

Nothing is damaged or bent, the engine is smooth at idle

I'm sure the diesel engine produces way more torque than the petrol, hence the question about the need for stronger mounts

 

The engine mounts on my diesel Jag (2.7ltr. S-type) were quite fancy with dampers, resulting in no steering wheel vibration at idle, just like a petrol. Maybe Chrysler are achieving the same with a very soft rubber. Most of the mounts I've seen are just a block of rubber bonded to two metal plates. There could be bad bonding from a batch, depends how the mounts are destroyed. Does the rubber fracture, or does the bonding come off the metal? Most diesels have a lot of vibration at idle, esp. 4-cyl. ones.

There's no evidence of a [T&C] Voyager in particular problem, should be a 100k change. Of course non Mopar cheepo geometry parts can also severely limit the half-life of a stress component. Check you are not installing the mounts :

- 90° out



- or even upside down

 

I think matgriff is referring to this mount or more like a damper. The way its made it takes compression when engine goes back on head. Sorry to say that it is very flimsily made as its easily ripped apart on rebound stroke.
Mine has went again after renewal last year, I'm just wondering if the main mounts have seen better days.
One pic is old unit, other is new one.

 

Yes Goggs, that's the one....

As you can see there is no possibility for fitting it the wrong way, 90 degrees out or otherwise (unless of course you re-use the bracket & fit a new bush)

 

I assumed [wrongly] that you just swapped out the bushing, not re-purchased the whole bracketry.
