It acts as a "spring" keeping moderate pressure between the ball/socket and the shift linkage arm, thus killing the vibrations which cause it to rattle.

Here are some pics to help:






Here's what you do:

1 - Get under the car & disconnect the linkage from the shifter. (Remove 13mm nut and pull linkage arm from shifter's "business end")

2 - Remove the two plastic bushings & slide the hose over the shifter end that connects to the linkage.

3 - Replace the bushings & re-connect the linkage.

4 - Test-drive the car. Expect the shifting to feel slightly tight, but very positive engagement in each gear. ENJOY hearing the engine roar thru the gears without that nasty rattle!
Thanks for the pics! So the piece with the blue hose around it - that goes into the bottom of the linkage, then the plastic bushings go inside that piece? What is the black piece that the blue hose is wrapped around?

Dave, you're a little confused.. It's just ONE PIECE, the blue hose is black on the inside.

The section of hose goes over the end of the shifter perpendicular to the direction of the bushings.. once it's on there, it's held in place by reconnecting the shift linkage. The top of the hose contacts the ball/socket and the bottom of the hose rests on the linkage just above the bushings. The spring pressure and plastic quality of the hose maintains pressure on the shifter & linkage such that the vibrations are deadend.

Ah! Gotcha - the hose slides over the "male" end, then that slides back into the bushings ("female" end). Hopefully I got it now I can take even the simplest concepts and make them very difficult

You sir are a genius - seriously. Today I went to Home Depot, got a 12" long piece of tubing that looked just like your pics, but mine had 1.25" ID. I cut a 1" piece off and followed your instructions. Once I got it on there, I thought maybe a 1 1/8" piece might be better and I will probably try a piece that size later. But any way - you nailed it! This eliminated about 95% of the noise, and a good 75% of the vibration I had, and the shifter feels more positive and a bit tighter. Hurst owes you big time IMO. Shame on them for being in the shifter business as long as they have and releasing a product that has to be modified to work better. Thank you very much for your post!

Default You're SO welcome!

MTAS - Glad to hear from someone who followed up on this... many seem to read it, ignore it, and go on suffering. It's very gratifying to help someone! Doesn't that feel & sound SO much better?

Now that you've installed the "Silencer", if you want to be sure you've done EVERYTHING to eliminate the rattle, get inside the car and pull off the shifter's rubber dust booty and spray some "Break-Free", or liquid "Creep" on the top side of the ball/socket (enough to "pool up" over the ball). As it penetrates the mechanism over the course of hours/days, it fills the void between the metal parts, thus creating a hydraulic "cushion", silencing that last bit of rattle!

My final tip comes from an "impulse purchase" I made over the weekend - I was in Advance Auto Parts and saw the Hurst TEE handle for $29, so I bought it and installed it in the parking lot.. WOW! I immediately fell in LOVE with the ERGONOMIC shape and the increased leverage, but after driving for a while and going WOT a few times as I'm wont to do - I realized this change in the shifter handle had altered its characteristic natural frequency response such that the vibrations coming from the engine/tranny were NOT exciting the shifter as much as they had when I was using the "Cue Ball" handle! This is a well-known phenomenon to Engineers, we work with it LOTS!

BTW, I also LOVE the "badass" look the meaty TEE gave my interior!

I recommend that ALL who have the "Rattling Hurst Blues" follow these ideas... it's my wish that you too create a Mustang experience a blissful as mine!

Matt.. this is mostly a "V6 engine/T5 tranny" thing, we've found it's RARE in V8/GT Mustangs, but thanks for playing!

ha, you only wish, there are tons of threads with the V8 hurst rattling. Different reasons but still many threads. Mostly due to lack of locktite though. easy fix

I feel very uncomfortable with the verbal imagery here.
