Body Mounting Bushings

[AZ4x4]

I've been going over a hood clearance issue and have been told that maybe my body mount bushings may be squished because of age. They sit under my 1968 Bronco and I don't know if they were ever replaced. My question is, how much lift will these give the body if the current bushings are indeed squished? Thank you.

If they were squished like mine, you're probably losing like a half inch of so. If you're having hood clearance issues you might want to consider adding a 1 or 2" body lift. I did 2 and it made a big difference.

Generally you can get easy access to the ones in the back and front for a measurement and close inspection. New/stock they had a large washer and were about 3/4" thick rubber bushing.

At one or more body mount location there will be factory shims to align & square the body and doors.

If/when changing to new body bushings it is critical to use shims as necessary to align the body to the frame for a nice fit....lack of shims and/or improperly installed body shims almost always result in poor fitting doors & door alignment issues.

Its very common for old-original body bushing to squish down and deteriorate over time. The new poly bushings, with a modest body lift, like WH sells are really nice!

EDIT: I just read in another thread where you're having clearence issues w/ your air intake. Here's the answer. This kit is advertised as 1", however taking into account these are NEW bushing, and you're old ones are probably squished down, you will probably see a net result of about 1 1/4" to 1 1/2" of added room under the hood http://www.wildhorses4x4.com/product/Custom_Body_Lift_Kit_1in

A member named "frenchy" sells a set of larger rubber body mount pads that only lift the body 3/4", without loosing the sound insulating qualities that poly won't provide.

Use of shims?

What would shims look like, are they basically just washers?

 

[jckkys]

Yes. The idea is just to keep things straight.

Cant stress this enough!!! Make sure when u do this you pay attention to where the shims are on the old bushings. I Did not and when i was done i had lean to the drivers side. Upon closer inspection of the debris pile of old bushings and stuff i noticed 4 washers 1/8" thick that were suppose to go on the drivers side bushings to level the truck. At first i thought i had the "bronco lean" but I when i measured the distance between axels and frame and frame to floor and found it all to be level, that was when i noticed the washers. Just remember to pay attention to where the washers are. This will keep door gaps and good and the body level

Adding to this proper torque specs are paramount on body mounts to ensure even and proper compression so the rubber or urethane donut is loaded to do its job. On urethane mounts it is typically 85 lb ft of torque.

Here are my body mounts, all new, with hardware and are powder coated black.

I installed a set of Frenchy's bushings. Very happy with them!
