My Hurst is vibrating all to heck. Especially when under strong acceleration. Are there any ideas of what I can do to help this??? [img]style_emoticons/<#EMO_DIR#>/headscratch.gif[/img]


Sorry to start another Hurst thread!





Edited 2/6/2006: I have no issues with my Hurst at all now. I think it was just needing to break in more. I definately recommend this shifter to everyone!!!

 

Mine does it as well,really it only does it when I get close to the top end of a gear. Not in 5th or 4 th if I am just cruising a street. I did alot of searching the net for solutions on this, guys with all kinds of cars have this problem. Some put a damper like a old sock under the boot to help.

 

Really?!? A sock under the shift boot? I don't think that will solve it. It would barely fit with the dust boot. I'll probably try it anyways! Thanks man!

 

Well if I ditch my Steeda for vibrating I won't get Hurst! I fixed my steeda from vibrating too much by putting a 3/8" thick spongy silicone foam between the shifter, between and around the 2 threaded rods. Just don't tighten the nuts too tight afterwards.

 

You're talking about the 2 threaded rods at the rear of the shifter?

 

yeah

just find some foam rubber, like a kneel down pad or something and cut it up into a rectangle and push it over the 2 rods/studs. If the stuff is really spongy, go thicker and tighten it down more. Don't tighten the 2 nuts down real tight and let the rubber do its job.

It will work

 

I just installed my Hurst yesterday. Noticably "ker-chunkier", due I believe to the polyurethane bushings instead of the cushy rubber stock ones. I've heard of replacing the urethane with the old rubber as a solution, but haven't tried it. This would likely address vibration issues as well, as the urethane transmits a lot more "feel" of all types, back to the stick and the cabin via the floorboard.

The most noticable thing is the loss of mechanical advantage due to raising the fulcrum point, which shortens the throw and increases the effort. It will never be "snicky" or like velvet with that change. IMO, Hurst went a little overboard with the fulcrum position, but I'm keeping mine...

 

Thanks for the replies guys!!!

 

I used the stock rubber bushings.....no vibrations on mine.

i wish i could use them on mine

 

I could be way off base here but I have been told by many different people that will defeat the reasons for the Hurst.

 

B&M uses the Stock Rubber Bushing, happy to report no problems, a great shifter!

 

I used the Hurst red polyurethane bushings on my car. No vibration issues, added noise or anything. I made sure that the metal sleeve that I took out of the stock shifter had the "lip" against the bolt head on the front 10 mm bolt, used white lithium grease for the plastic bushings on the 13 mm nut which I tightened just "snug", and also just tightened the two 10 mm bolts that hold the rear of the shifter just "snug".

Like I said, no vibrations, no extra noise, or heat coming in from the Hurst. Just firm and positive short throw shifting just as advertised.

 

I used the stock rubber as well. No extra noise. I assumed the shifter would work just like it would with the urethane bushings. I wanted to use the provided urethane, but the instructions said to use the (2) stock metal sleeves in the front bushing to re-install But my car only had one long metal sleeve, one side is where the 10mm bolt mounts up against and the other side mounts to the transmission. But the metal of the other side is even with the rubber so when mounted against the transmission it would tighten down against the tranny. When I tried to use the provided urethane bushings the sleeve wouldn't go all the way through. It was about 1/8th of an inch short. The urethane would have been mashed against the transmission. This didn't sound like a good idea, so I used the stock rubber bushings on both ends.

Has anyone used the stock rubber then wnet ot the urethane? Any noise increase? If not I may call ford and see if it is possible to get the 2 piece metal sleeve and try the urethane bushings.

 

Since were all talking about the Hurst install, I have another question. How did everyone handle the rubber boot at the top?

The boot doesn't really attach to the Hurst shaft like it does on the stock shifter. The stock shaft is round and larger in diameter. The Hurst is more of square shape and not as large. I was really only able to attach the boot by placing it over the area where the two torx bolts that hold the top part of the shaft attach. Is this how everyone else did this?

 

So it looks like I should maybe swap out the bushings for the stockers and/or back out the bolts a bit...






I also attached mine over the torque bolts.

 

Well, tonight I noticed in a quiet area on my drive home when I really get on her you will get a slight vibration with noise even with the stock bushings. I think noise just transfers up through the shaft. If you look at the stock shifter you can see that Ford placed the top shaft inside what looks like a rubber shaft. I think they were probably experiencing noise issues as well during NVH tests and concluded that placing the shaft inside the rubber mount in the bottom part off the shifter eliminates most of this. Maybe placing a piece of rubber around the shaft could help the vibration?

I am also wondering if there is a possibility of damaging the transmission with these shifters. Mine is much more notchy with this setup and requires quite a bit of force to get into gear. Usually first is the worst. It also seems that coming out of gear requires much LESS force than usual. The shifter does snap into gear rather well but it seems so much more different than the stock setup. Almost just doesn't seem right. It probably is and I'm just being paranoid. Do things feel okay for you guys? Will the stops in the transmission prevent damage?

 

I just installed mine last night. I am very happy with the throw. Its like day and night. But like you guys are saying about the notchy feeling, i'm getting the same thing. Coming out of gear its ok, but putting it into the next gear its a bit of a struggle. I might regrease all the bushings again.

 

well i just installed the hurst i got for my birthday from my kids, and i got to tell you it is great, no noise and just a hint of vibration. ( only if i am holding the shifter down on the chrome saft area).

DENVER05GT there should of been an adapter bushing looking thing that slides down the flat chrome handle with a groove around the outside for the oem boot to fit into.

 

I've talked to a mechanic friend of mine who said something similar to what someone else said in the other Hurst Thread floating around here and that is that due to the shorter throw and less mechanical advantage there is more "force" required to get the shifter in gear. I was wondering about this myself and maybe that is why Hurst also made the shifter stick a little taller than stock (with the chrome handle). Without mechanical drawings of each to confirm though this is kind of speculation with the mechanical advantage scenario but it seems logical.

It does seem to loosen up some with time though.

I remember when I installed a Hurst in my '94 GT... installation was done from inside the car and easier IMHO. The throw was much shorter than stock and also firmer. I drove that car over 100K miles without any tranny problems.
