Use a ball joint press. You can get one from Harbor Freight. You'll most likely need the accessory kit as well. You can use the press in different configuration to press the old bushings out, and the new bushings in. Even the front upper bushings in the axle can be pressed out, although it may be a little tricky setting up the ball joint press to do the job.
The control arm bushings are pressed into the control arm. You must use a press (ball joint press with proper adapters, etc.) to remove and install bushings. You may need to heat old bushings with torch to remove bushings from control arm. If you are comfortable with this then here is what you need to do: Remove wheel. Use safety glasses while removing ball joint stud from steering knuckle. Unbolt control arm from vehicle. Change bushings. Install control arm in reverse order. You should get an alignment after doing any front end work.
As far as I know nobody makes bushings for front control arms of Altima 93-01. Many Internet stores sells complete control arms with bushings and bell joint. I've found one that sells at 79$.
Try this site, it helped me a lot. http://www.mn12performance.com/mn12parts/fsk100/fsk100-install.htm
No
On my truck during a routine brake job. The truck was on the rack. At 99,999 miles, all the bushings of the front end had disintegrated. This is a2001 Lariat F 150 Extended cab.
I do not believe they are replaceable, I believe thay are available aftermarket.
Since The Villager is of unibody construction, there are only a couple things that can be considered "subframe bushings". Sway bar bushings (front and rear), rear leaf spring bushings, and the most likely, control arm bushings.
change the sway bar rubber bushings and sway bar link bushings
Check the control arm bushings and any other bushings that may be worn.
bushings (control arm)
probably or there part of the same piece ....normally there's multiple bushings on a lower control arm ...i guess it just depends on the vehicle and its probably easier to replace the whole arm rather then individual bushings.
Yes, generally after any major work on a front end a re-alignment is neccessary. Replacement of bushings and control arms could be considered major work.
