Best brand on motor mounts

As I have the typical clonk (feels like a worn universal joint on a RWD) when driving and the front end of the engine lifts a little when standing still shifting between R and D, I believe my front (right) motor mount needs replacement, question is what brand to choose and also if to go hydraulic or solid?
Looking at the supply from Rockauto, Dea Marmon seems to be the favorite.
Another question is how to get a FWD car up on the jack stands if doing this on your own?
Any inputs on the topic is welcome, as always

I have no dog bones on my car from factory, but have been thinking about creating some homemade one’s as I know they would take a lot of stress of that front mount.
However, since car has run 124k miles and likely still have the original front mount, I figured replacing it would be a good start as I don’t drive that much anyways

FWIW I have had a set of Ranger's Rods installed since early in his "production run", almost exactly 11 years ago. Many, many WOT runs, top speed runs, radical shift work in the farm road twisties east of here. NO radiator cross brace flex, no problems, no worries. And no broken front center motor mount. BUT the radiator brace mounting areas are not rubber buffered so there is a bit of busy engine noise transmitted to the body. Not a problem for me but its most definitely not "Cadillac".

The most elegant solution is probably the HD center mount from Northstar Performance. It's semi-solid and rubber buffered so there's much less engine noise sent to the cradle frame. Bulletproof and invisible.

Sub, thanks for your "field-test report" on the Ranger rods.
The idea I had regarding avoiding the engine noise transmitted to the body through the torque rods, is to use two 90* brackets and put a smaller engine mount in between, so that when the engine pulls towards the firewall that rubber cushion gets compressed which it should hold for, and on the way back towards the radiator there shouldn't be much load on it.

Totally with you regarding the HD center mount from Northstar Performance, it would the best and most elegant solution, but unfortunately also a top dollar solution as I get to pay it twice with shipping and tax included ending up 400$

I'm leaning on placing an order on the DEA / MARMON RIDE CONTROL (hydraulic mount), that will cost me 62$

Yes with bracket, i file the holes for mount in bracket some to allow some wiggle as makes life easier. Also I've had to shorten the bottom bolt to get them in. Don't think removing from top any easier, haven't tried. Assesmble loosely and put in then put all bolts in then tighten everything down makes life easier.

Thanks!
I will let my favorite mom&pop shop do the job, but still wanted to collect whatever tip I can give him to make the work as smooth as possible.
Is there anything connected to engine (wiring, pipes etc) to look out for not getting too stretched when dropping the subframe to get it out?
 
#11 ·
You don't have to drop subframe. If equipped with dog bones take them loose on one end so motor can be raised. May be easier and believe i did was to remove oil filter housing(10mm head bolts) and wiring to have plenty of clearance. I'm sure I'm forgetting something small but biggest thing was to shorten the stud on bottom of the mount to get it back in, the old one will flop around and is easy to get out.

Got a new front mount installed yesterday.

The mechanic showed me the old one that had a 2’ long crack in the rubber part, also IF you turned it upside down some oil came out of it, no oil leaks showed before removing it however.

In all it was not totally wasted as I can imagine they can be, but bad enough to motivate a replacement.

The result of replacing it didn’t make that much of difference, I still get that little clunk as a worn U-joint on a RWD car would feel.

Inspected the rear engine mount today and found what looks to be a crack (looking from the drivers side on the mount)
But when looking at a new one (see pict 2) I get a bit uncertain, appreciate if someone who knows how it should look can confirm that its broken
After some thinking it’s getting more and more obvious that the gap I see on the driver’s side of the rear engine mount, is the end of the diagonal slot that is dividing the upper part of the mount.

The only way to know for sure is to get under there and have another look.

I will do what I should have done from the beginning; do a proper inspection on all mounts, feel over sub frame and bracket bolts etc, but consult my favourite mom&pops shop as he has a lift so we can get a good access on all the concerned parts.
