Wgnc34 Engine Mount Replacement- When Are People Replacing Them?

[RS4StagMan]

I did a bit of a search and it didn't come up with anything meaningful.

I wanted to know at what approximate mileage people are replacing their;

A) engine mounts and

B) gearbox/transmission mounts

Apart from slight vibration at idle and clunk of engine when shifting from drive to reverse, what are other symptoms?

Also I understand that the C34 Stagea 4WD uses the same as the R32/R33 GTR engine mounts.

Do most just replace with aftermarket Nismo ones ( a bit stiffer I think) or other aftermarket ones? Anyone priced genuine ones lately?

I changed my rear transmission mount a few weeks ago (1999 S2 Automatic RS4)... I posted it in the "what have you done to your stagea lately"

There was a slight vibration under load which got louder in the cold and wet weather. It has made SO much difference, I had been troubleshooting the vibration for ages!! My car only had 140,000 on the clock. Part number: 1132001U01 and was about $200 with the replacement rubber bushes for the bottom transmission brace. From my research I couldn’t find a Nismo equivalent.

Supposedly its a bitch to do the engine mounts, but as I haven’t done it (only heard from my mechanic) I could be wrong.

Just ordered the Nismo set from Nengun: 2x eng mount, 1x gbox mount: cost $268.88. It was the cheapest I could find from a trusted supplier...

For the record, I think my shell has around 160000km on it, but the engine and gearbox were swapped in about 20000km ago: not sure how old the shagged mounts are...

Do you have any pics or description of the suspect trans mount, any DIY instructions/tips that you would like to share? How did you diagnose it in the end? Any pics of the one you took out?

How hard would it be to replace without a hoist?

Was yours also idling roughly as well as getting the vibration under acceleration? Assume there was no vibration when just cruising. Was it rev specific?

Found this pictorial, I can see how it all goes together now.

Sorry mate don't have any pics of the old mount, basically the "insulator" (as nissan calls it) part of the mount was not as thick as the new one. This caused the transmission to droop and as it was on an angle would vibrate under load. In the later stages the vibration was really loud (especially when wet) as the "insulator" part had worn away and it was just metal on metal. Wasn't rev specific but i noticed it would be louder stationary.

I only found out it was worn from the muffler shop (hats off to HiTech Mufflers) as i was thinking it was my exhaust vibrating!

I wouldn't want to try changing it without a hoist, keep in mind you will need to support the transmission (jack or what ever) while you remove the transmission cross brace.

The mount is only $100 but the other 4 rubber pads (11248) should be replaced too (mine were totally gone and added to the transmission drooping further). These are $25 each (rip off i know).

Hope that helps buddy.

Thanks Adrian, I will be sure to check mine when I'm next under the car.

Was the car also idling slightly roughly (side mirrors slightly moving) as well as the metal on metal vibration when stationary?

Any other owners care to share engine mount, trans mount replacement experiences?
