Smart Car 450 Engine Mount Replace Part 2 (Engine Mount)

Followers will be aware that I have a loud banging noise coming from the rear of the car, every time I go over a bump. Having changed the driveshaft, sway bar (anti-roll bar), bump stops, and checked the X beam I still have a banging noise, so in the following three videos we are going to change the gear box engine mount, engine mount behind the driver and the terrifying center engine mount which my local garages have refused to do.

Center mount is a complete pain. The red power flex inserts are a better option than filling with silicone. Bumper off and xframe. You will need to drop the drivers side engine mount down a tad, keeping the bolts in place. Support the gear box again with the jack, take the centre bolt out of the front mount (essentially splitting it), but the bolt can be tricky to remove due to other components. If your going to replace the full mount, the top part will have to be unbolted through top of the engine (if you have aircon, it can be difficult) with a very long extension. The other half from underneath, but go easy on those bolts onto the engine as they tend to snap (apply heat if required). Then replace every thing in reverse with the mount split in half and finally attaching the center bolt in the mount. With two people this will take 4-5 hours.

Thanks for this, I hadn't thought about taking the side engine mount to create space. It does look like a pain but I will follow your instructions and have a try over the next few weeks. Fortunately, I have a van so I can take a little longer as the other vehicle will keep me on the road. I'll let you know how I get on.

Is it possible to change only rubber bushings with new or polyurethane ones? It is cheaper

[@shed52]

@@milanjovanovic6259 Rubber bushes are moulded into the new engine mounts. Its Ok to use them like that without polyurethane bushes and you will have less vibration. I do however like the polyurethane bushes on the centre mount.

Have you done the centres mount yet? Common practice is the leave current bracket in place, and replace just the bushing. You can buy power flex inserts for the bushing. Supposed to really improve the feel of the car, but more vibrations when idling

Hi, I have had a look at this one, which is high up on my 450 and difficult to get at. It looks really difficult to get at. I will take your advice and get some PowerFlex inserts, If I do this one, I don't want to take it off again. On the 450 it looks really difficult, so I'm going to order extended bolts (drop bolts) and lower the whole subframe.

Hi, aftervreplacing the two engine mounts the situation is not solved?

[@shed52]

After replacing two engine mounts it hasn't solved the problem. Looking at the center engine mount it looks split so I will change the center mount next.

[@ilvale6439]

@@shed52 I have your same problem 😥

[@shed52]

Yours is the centre mount as well? I went to two garages that didn't want to do the job.
