I remember somebody was attempting this
any progress?
im getting the parts list together now...

I figured there was too much in the way in the later models. Haven't started the lower mount aircraft cable snubber, either.

the front support side should be straightforward, attachment to the engine is another matter, anyone have a good closeup pic of the side of the engine closest to the radiator? Someone just needs to make some cardboard templates of an engine side mount and weld it up...

Pics would help :) Also, look at Rockauto for the dogbones, the dealer wanted $75 retail, $50 list, I got them for $13 each...

I think it was Logan that was attempting it.

You guys are talking about the upper dogbone engine mounts right? Dont want to sound like a dumbass lol... Whats the benefit of putting eldo bones on an STS?

They quit using the dog bones around 2000. I think he is talking about adding a set.

"Eldo bones on an STS"........The top of the drivetrain rotates toward the firewall upon moderate or hard acceleration due to torque (power doing work), therefore placing great strain on the single left (front) motor mount and eventually destroying it.

You need to visualize the layout of a FWD engine layout: The "front" of the engine is on the passenger side of the car. The "rear" or bellhousing end, is toward the driver side. The "left side" of the engine is in the front of the car, the "right side" is closest to the firewall. Therefore, in a left-hand rotation engine the torque tends to lift the front of the car and squat the rear. It all looks trick, but is grossly wasteful of drive horsepower application to the ground in a FWD setup. (Ever seen a FWD car do a wheelie ????)

Dogbones, solid motor mounts, or snubber cables/brackets limit the amount of drivetrain rotation under acceleration and allow more torque to be applied to moving the car forward as opposed to lifting the front of the car.

The more torque plastered on the pavement = faster 1/4 times and speeds.

i also removed all the components so you can see how they are made.

if you are wondering what the disc is welded to the mount,it has rubber sheet
glued to it.this then acts as a pressure pad against the suspension mount.

impressed
but im way too lazy to get that involved

..........so if you can't buy it over the counter, chrome plated, it doesn't qualify as a legitimate modification ??

:sneaky: Sure am glad that the people that design and market good, reliable, effective aftermarket engine and chassis equipment don't have that attitude.

VERY nice. I'm impressed. It makes my home made water pump socket look shabby by comparison.

im lost?
was that a shot sub?
i never said it wasnt a legit mod
im truly impressed and i dont care about if its chrome
im just way too busy with so many other things to try and even attempt to build something like that myself

Submariner409
10-25-08, 09:33 PM
Yeah, that was a shot. Not at anyone specific, just a random discharge at the "I want it now" whiners and bitchers that refuse to believe that worthwhile modifications to FWD Northstar vehicles don't come in cutesy boxes.

Jay, You know better.......Sorry I bounced off you to make a point......

10-25-08, 09:35 PM
fully understand
just didnt realize where it was coming from
yea i have no problem making something just not enough time anymore to even start it (hence why im never online anymore)

ordering the Eldo brackets and fabbing something up I can do
starting from scratch and mapping things out to make precise measurements, until summer vacation (oh yea im a senior...) that isnt happening...

How important are these things on a Eldo? Mine have the ruber bushing torn up on the drivers side and there both very lose

Those are technically "torque struts" and prevent the engine from rotating toward the firewall under hard acceleration, thereby breaking one or more motor mounts. The lack of any sort of torque control on the later Sevilles and Devilles is why you see so many questions on broken front motor mounts and AJ's solid front mounts for Seville/Deville Northstars.

Get new dogbones......they are there for a good reason.

Jay.......You have a VoTech section at college?? Maybe a metal or auto shop ??? Try them.

Nah
