Details: DIY Volkswagen T4 suspension repair from a real master for the site my.housecope.com.
The front suspension of the Volkswagen Transporter T4 (see Fig. 378) consists of a beam (cross member) (53), upper (29) and lower (22) levers, torsion (rod) springs (39), and a stabilizer (48). Hydraulic shock absorbers (2) are used to damp suspension vibration and ensure reliable contact of the wheel with the road surface. The front suspension beam is attached directly to the body and supports the front of the powertrain. The individual suspension parts can be removed independently of each other.

Volkswagen T4 minibuses were produced from 1990 to 2003. Due to its reliability, ease of use and a wide range of model range, the car has become extremely popular both in Europe and among motorists from the CIS. Along with a huge number of advantages, the Volkswagen T4 has some disadvantages and weaknesses that the future buyer should be aware of and pay attention to when buying.
In general, the Techik's body is very durable, made of galvanized metal. However, this material is susceptible to prolonged exposure to moisture. Significant amounts of rust on the body are rare. But a rusty bottom is a very common phenomenon. Corrosion often affects the underside of doors, sills, gutters and rear fenders. Particularly vulnerable are cars that have been operating for a long time in conditions of poor-quality roads, a large amount of reagents on the roads in winter and a humid climate. How to check? To check the condition of the car body, it is necessary to carry out a thorough visual inspection on the overpass. It is necessary to expose the surface of the body, especially the underside, to light mechanical stress with your hands, especially at the seams. And it is important to remember that this model (T4) is no longer produced and therefore practically all cars have problems with paintwork.
Both diesel and gasoline engines have vulnerabilities. Diesel engines are characterized by periodic breakdowns of the high-pressure fuel pump and the glow plug control system.Turbocharger breakdowns are not uncommon for turbo diesel engines. In gasoline engines, the most common malfunctions of auxiliary electrical equipment: starter, generator, ignition coil and others.
First of all, to check the engine, it is necessary to measure the compression in the cylinders using a special device. The main "symptoms" of a problem engine are as follows:
the car does not start well or does not start at all;
exhaust gases are blue or white;
oil on the dipstick with foam or white or light blue splashes;
the coolant in the expansion tank is dirty brown;
third-party noise when the motor is running;
poor cravings.
Automatic transmissions are especially problematic. In them, torque converters regularly fail. But there are many problems in mechanical engineering. Bearings and gears wear out rather quickly. As a result, gear shifting becomes difficult. By the way, the gearbox is considered one of the problem areas of the Volkswagen Transporter 4. When checking, you first need to check the quantity and quality of oil in the gearbox. It should be clean, level. Next, you should shift the gears, on the spot and while the car is moving. In a serviceable car, gears are switched easily, smoothly, without third-party noise, tapping. The gears do not "pop out".
The Volkswagen T4 suspension is strong enough. Its condition depends on the operating conditions of the vehicle and the quality of the roads. In the front torsion bar suspension, the upper ball bearings fail - 50 t.km., the stabilizer bushings - 30 t.km., the silent blocks of the lower arms will last a little more than 60 t.km .. Rear spring suspension - shock absorbers move away 120 t.km ... without a fanatical load. When checking, you should start with a visual inspection. Defective parts very often have oil drips. All rubber components must be intact, free from defects and cracks. A faulty suspension creates characteristic noises while driving.
Breakage of side door rollers is a fairly common problem and one can say Volkswagen T4 disease. At the initial stage of the malfunction, the side doors close poorly, not always the first time. Over time, the door simply cannot be closed. In good condition, it should close easily and immediately. Therefore, when buying, you need to pay attention to this and open and close the door several times.
Expensive spare parts;
The gear lever is far away;
Weak insulation;
Vibration of window frames;
Bad optics;
Crickets in a torpedo;
Weak and long warm-up of the passenger compartment in the winter.
Based on the foregoing, we can conclude that, in general, the car at one time occupied a worthy place among its competitors, but due to the age parameters of these cars, it should be understood that the body is quite corroded. Therefore, when choosing a car, you need to make the right choice, conclusion and think over all the pros and cons. After all, there are many alternatives to these cars in the car market.
Here are photo reports on repair and detailed documentation on cars:
Cylinder head repair on Volkswagen Caravelle Т4 - ACV engine (AJT, AHY, AXG, AYC, AYY, AXL, AUF) (rus.) Detailed photo report. The ACV engine was installed on the following vehicles: VW Transporter T4 (70), VW Transporter T4 (7D).
Replacing the drive belt on the AAA VR6 2.8 engine (rus.) Photo report It's time for a little service. It is recommended to change the drive belt every 120 thousand, plus the fact that it is one for everything on this engine.Recently, the belt began to whistle, and why squeeze the maximum, in general, the replacement procedure is described in this report.
Determination of turbine overflow by logs, TDI engines, etc. (rus.) Photo report The most pressing problem in turbocharged engines is the occurrence of an overflow. This is especially true for diesel engines. the formation of soot in the exhaust gases leads to its rapid accumulation inside the turbine and wedging of the geometry. First, let's try to figure out how the inflation pressure is regulated, and then let's look at what the blowout looks like in the logs.
Power loss during acceleration, turbine underflow, description of problems, removal of logs and diagnostics (rus.) In case of problems associated with the loss of power during acceleration, both constant and variable loss of traction when driving. Loss of traction in "full throttle" mode or the transition of the engine to emergency mode (driving, but not pulling or pulling weakly) read this entire text carefully, and 9 out of 10 that this will help you establish the exact cause of the problem.

HolDeR "13.09.09, 12:32 Re: T4 suspension, changed everything, but the knock remained.
I also had some kind of knocking from behind. I changed the rear shock absorbers, brake discs, pads, hub bearings. I checked my fingers in the caliper. The knock still remained. Found the reason by chance. I began to remove the rear bumper (inflated), so that to remove it I had to open the taillights. And I found it .. It was knocking, or rather, the honey in the headlight blurted out. That is, it fell out and was inside the headlight.
As I found and remembered a bike from a car service: When a man came to them and said, he blurts out something, and what I don’t understand. They shook up all the suspension for him and the knock remained. After a long search, they installed it - a screwdriver snapped into the inside of the door behind the trim. The man himself removed the trim and forgot to take out the screwdriver, so she rattled there.
What is all this for? Besides, it is not always possible to find out the reason for the knock according to the description. You need to watch individually in each case.
