Subframe Bushing R&R Tool Rental

[bcredliner]

It is not likely you will ever have to replace the bushings again.

Considering stock bushings or meyle heavy duty oem bushings are about 150 for the set plus about 50 for Dave's tool rental its still quite the significant savings over poly. You could probably get 100k out of the stock bushings so you could do 2 replacements and rentals of Dave's tool and do 200,000 miles and still be cheaper than the poly replacements.

I'm all about poly in the right circumstances but the price premium would never be worth it in my opinion.

FYI - AFAIK, the HD;s are just as *hollow* as all the other subframe bushings on the market. I went with Lemforder when I picked up Lemforder rear shock mounts. Everyone is subjective brandwise..

The original bushings were somewhat hollow, but that's part of the design. The hollow areas allow for minimal movement side to side, and a little more fore & aft which softens the shock when power is applied. Most subframe bushing failures are fatigue related, where the center metal alloy ferrule separates from the rubber, which allows far too much movement, and misalignment of the subframe.



I don't think the voids make them failure prone; it seems like we're seeing more failures now, but the vehicles we are dealing with generally have upwards of 100,000 miles on them, so failure at that age shouldn't be a surprise. What bcredliner said is true; few of us will replace the bushings twice.

The poly bushings differ from stock in that they have no voids; I don't think that's really a positive or negative attribute, just different. It'd be interesting to see what a set of poly bushings looks like after 150,000 miles though.

FYI, when I removed the OEM bushings they were fine at 106,000. I was going for better handling to compliment the other suspension upgrades I had already done.

[jsoto]

OT....but I'd be curious on how the feel of HD bushings up front vs. not is *comfortwise*.

[bcredliner]

Not sure I understand your post.

Are you asking if the poly bushings result in a stiffer, firmer or rougher ride?

looks like i'll be doing stock now due to finance situations. i need to do a bunch of suspension stuff like thrust arm bushings, balljoints, left axle due to torn boot, i know i can just do boot but dont know how long its been torn plus it'll make doing the balljoints easier i hope. front brakes will be soon after that.

Replaced my bushings yesterday. Thanks for all the tips here. The spesial tool is a must I must say, and heating them to get out and soap to get in.

David send you an email yesterday in regards to renting the tool if its available? Let me know! Thanks
