Replacing Rear Torsion Beam
#2
The left trailing arm bushing is cracked. Instead of replacing the trailing arm bushings I'm inserting another torsion beam. A used beam I found at a local JY is in great condition.

For $75 I also got the rear hub assemblies with ABS rotors, rear OEM calipers & brackets, and slotted brembo discs. The lateral link and control rod was included but I'll be replacing those.

I'm also throwing on new rear baffle plates (disc splash shields), swapping out the rear pressed hub assemblies, 4 red powder coated calipers & brackets, and 4 used slotted & drilled brembo discs.
After I powder coat the OEM calipers I'll rebuild them with a Nissan caliper kit. I'll also turn then paint the brembo discs.

That would be great if you could detail the process! Mine isn't looking as unmolested as I'd like. Might also be following in your footsteps.
If nothing else, how replacing the bushings and link goes and which replacements you used!
Thank YOU!

It's held fine since then.
With only 5 bolts (shocks, trailing arms, lateral link) mounting that beam is a simple but time consuming job. Oh, don't forget the wheels, calipers, their brackets, parking brake cable, and ABS sensor that need to be removed. The tricky part is the order it needs to be done.
On my 98 I'm inserting new splash shields and swapping the wheel hub assemblies.

Reading post 50 in that thread states the trailing arm bushings can be installed by just removing the shocks and trailing arm bolts. The ES 7.3120G Bushings will fit the trailing arms along with these SuperPro SPF1942K bushings. They're both polyurethane.
Read this B15 thread for pictures and steps on replacing those trailing arm bushings:

As seen the rear beam was left on the B15 Sentra.
The beam can also be left on when replacing the lateral link. There's no aftermarket replacement for the lateral link. Only the small control rod has replacements (Kuos, Febest, Dorman...)

The rubber trailing arm bushings are fine on the used rear beam I'll be inserting but might as well upgrade to the ES bushings. I ordered them today at Autozone for $32 total. Much easier to replace them with the beam sitting in my garage.
I already refurbished the rear beam with rust converter and semigloss black paint after using a 3M rust stripper. To avoid harming the paint I'll try to skip the torching. I'll take pictures when I start it in a day or two.

Here's the refurbished beam I'll be installing
After I insert the trailing arm ES bushings I'll start the replacement sometime next week. If I take enough photos to create a HowTo I'll delete this thread and start a new one.

I'm only replacing it because of the heavy rust and the left trailing arm bushing is cracked. I remember one former member from Canada posted that one of his trailing arms broke on him. Most likely caused by excessive rust. The trailing arms are nowhere near as solid as the beam they're welded onto.

Cleaned out those rubber bushings on the trailing arms. Used a large hole cut saw to get most of it removed. Used a sharp blade, small fine wire brush, and sandpaper to clean off the remaining rubber.
Coated the ES bushings with the grease provided and pressed them in easily with a C clamp.

She drives much darn smoother now!
No more rear wobbling when hitting bumps. It also has less understeer due to the ES polyurethane bushings I installed in the trailing arms.
It wasn't just the rubber left trailing arm bushing that was cracked on my OEM beam. When I removed the lateral link off the beam the bushings got torn.

Hey jholley! So glad i found your thread! I just purchased a '99 GLE and I know it's beam needs to be replaced. Doesn't look to complicated to do exceptthat I don't know how to do an alignment. Plus I'd really like to get something that can handle a bit more abuse and preform better than OEM. Also looking to do quite a bit more to this vehicle after a while. I'm pretty knowledgeable about cars, but I'm no pro just yet. Still learning. Any chance of contactingyou to pick your brain?

Bubba - There's no alignment to do on the rear of the fixed beam. There's really not much to do to improve it aside from the bushings. It's a descent suspension, the Russell Link does a good job keeping the rear wheels planted. You can add an addition sway bar to stiffen it up a bit, but there are negatives to that as well.
A sway bar adds unsprung weight to the suspension and also makes the rear a bit twitchy, which gives little to no feedback right before the rear slides out. Several members have experienced this and the damage associated with a loss of control during a high speed sweeper.
I speak from experience, the car rides much better without any additional bolt on stabilizers in the rear and with the right suspension, handles just as well with much needed feedback to keep the car in control on those twisties.

With the entire rear setup disassembled the first step is to tighten the control rod onto the lateral link and the rear beam horizontally. Raise the beam with bottle jacks on both sides high enough to get the trailing arm bolts thru the chassis. Only hand tighten those trailing arm nuts & bolts. With the shocks left off raise the rear beam on both sides with trans bottle jacks high enough to get the lateral link onto the chassis. Hand tighten lateral link bolt onto the chassis. Raise the beam more trying to get it as horizontal as possible with the lateral link. With the lateral link connected to the right side of the beam the left side will raise first. Fully tighten the lateral link and control rod nuts & bolts. Lower the beam to slide the bolts thru the shocks then fully tighten them. With the beam loaded with the shocks now fully tighten the trailing arm bolts. All nuts & bolts in this setup requires 72-87 ft/ lbs besides the control rod nut & bolt connecting it to the lateral link. That requires only 43-58 ft/ lbs.
Download all FSM forms for your 99 Maxima from this link
http://www.boredmder.com/FSMs/Nissan/Maxima/1999/
The RA.pdf form defines this setup.
If you're not dropping the rear beam and only balancing it then you only need to fully remove the shock's nuts & bolts. Loosen all other nuts & bolts to perform the balancing.
EDIT: If all the bushings are fine and the beam is only heavily rusted then let it be. The beam is solid and has only bent on a few maxima's from what I've read. Measure the center of your rear wheels to the front, top, and rear sections of the quarter's lips. Both wheels should measure the same distance from the quarter's lips.

Thanks guys! I got a bit confused there for a second. I was reading kinda fast and thought I was understanding that there was a rear alignment to be done. Hah
Now, I didn't get to take that good of a look at my car yet. I just bought this puppy. But there's a kind of stressed noise that comes from the rear when you coast and break. It's a ghost noise though, so I haven't been able to catch it to find the source. I'm believing it's the link bushings by guess.
But looking for that noise is what made me look at the beam. To me it looks possibly more than rusted from what I remember. I'll have to get under there again. Depending on how corroded it might be, even though I don't remember seeing anything bent, should I still not bother changing it out?
And from a performance angle, I'm also wondering about whether I should change to an independent setup. This is my first time with a car that's had a connected rear suspension. I've heard that it does wonders in cornering for Ford's new RS, but how wrould that play on a car this size vs retrofitted A-frames?
Mind you, I'm coming from a 99 V6 Accord that I pretty much learned everything I know about suspension so far on. One thing's for sure, this looks a TON less complicated.

If you're lowered, forget the RSB altogether.

If the lateral link or trailing arm bushings needs replacing you can do it while leaving the beam installed. Nearly all the side attached parts can be left alone. Read my earlier posts for more details on that.

Hmmm I have a fair amount of rattle from the rear of the car when I go over speed bumps. I keep wanting to blame the front sway bar bushing, but it definitely sounds like its coming from the rear. Could this be the culprit? Bushings gone bad?

To check the rear hubs wobble the rear wheels around while she's raised.
