Peugeot 307 Lower Engine Mount

Post by Bannedbiker »

The lower engine mount seems to be a common problem with some Peugeot and Citroen models. When I had a Xantia a few years ago I replaced the rubber bush part of the mount by cutting the old one out and pressing a new aftermarket replacement with a large vice.
So when I bought my 307 a couple of years ago, the lower engine mount was one of the parts I replaced (to cure a judder when taking up drive).
Recently I noticed the judder was returning and on inspection was cracked, so I replaced the bush part of the mount.
Image
I fitted a polybush one made by Powerflex, unlike the original type it just pushed with fingers, no hydraulic press required!!
The car is now wonderfully smooth to drive, with no judder.
Image
This may help someone, it was a 65mm bush I fitted to my 307, ironically the same size as on my Xantia years ago, and the Powerflex part number is PFF50-420 for a yellow bush.
Better add I don't work for either company.

Thanks for that BB :D

Now that's interesting.. I wonder if that might work as a substitute bush for a Xantia?

Looks exactly the same size as the one I replaced on my 1.9 td Xantia a few years ago.
I'll measure the old one when I'm next in the garage and put the dimensions on here.

Keep an eye on the polybushes.

We fitted them to a P38 Range Rover. After 2 years and about 16,000 miles they were knackered and had to be removed. The play in them made the car feel like you were about to loose a wheel if you caught a pot hole or manhole cover. The other thing to note is it took hours of cleaning up before we could replace them with genuine LR bushes as the water had got in behind the polybush and caused corrosion in the trailing arms.

Be interested to see how this lasts though :)

I'll get the dimensions done first. Outside "tube" of bush is 65mm diameter by 40mm wide, and inside tube of bush has a 10mm diameter hole and is 55mm wide.
Regarding the life of polybushes I'll let you know if they fail quickly. Powerflex seem to be one of the better suppliers out there so fingers crossed it'll last ok.
I also have a Mazda MX-5, and the quality of suspension bushes available for that seems to vary widely. For that reason I'll be keeping genuine Mazda rubber bushes.
I saw photos of the result of poor quality polybushes fitted to a MX-5 that was doing track days. They had lasted about five years from memory when the owner complained of poor handling from the rear of the car. When the wheels were removed the metal centre tubes (which were aluminium) had corroded increasing the diameter and eventually seizing. The result was the wishbone was forced to twist as the bush wouldn't rotate and fractured from metal fatique. If they had been stripped down and lubricated periodically they may have been ok, but having aluminium tubes didn't help. Powerflex seem to use stainless tubes to prevent corrosion.
I'll see if I can find a link to the failed MX-5 wishbones.
But on a positive note, just returned from a 20 mile round trip and it felt great so far!!

I replaced mine with a Powerflex one a couple of years ago. Was a huge improvement.

My mistake, the polybush mount is made by Powerflex, not Superflex.
Nice to see someone else has had one for a couple of years.
I was expecting a silicone grease to be supplied, a friend of mine with a Triumph GT6 used silicone grease with his polybushed suspension.
However, the supplied lubricant was copper grease so I used that. I'll probably end up re-greasing once a year as it's easily accessible once under the car.
